Raspberry Pi 4 Ubuntu Server / Desktop 18.04.4 Image (unofficial)

Fine, I'll do it myself
No Official Pi 4 Support? Fine, I’ll do it myself

This is a unofficial distribution of Ubuntu Server 18.04.4 for Raspberry Pi 4. It is provided with the purpose of letting us all play with the new Pi 4’s new increased RAM and other capabilities until Ubuntu’s repositories are updated with support for the newest Pi.

I want to thank all the commenters on this article and my Ubuntu Server Installation Guide for Raspberry Pi 4 who have contributed a ton of fixes to help get the image to the point it is at now! I also want to thank anyone who has reported issues or pull requests on the official GitHub page. This has truly been a collaborative effort and I expect it will continue to be until official support is released.

GitHub Project Location

The image and source code to build the image are open source and freely available on GitHub:

https://github.com/TheRemote/Ubuntu-Server-raspi4-unofficial/

Update Bootloader Firmware First (using Raspbian)!

One important new thing to understand about the Raspberry Pi 4 vs. older Pis is that the 4 now has real onboard firmware that is on a special chip separate from everything else. Older Raspberry Pis did not have real onboard firmware and loaded all of their firmware from the SD card every single boot.

Before you install this image you should run Raspbian and install the latest firmware using this command:

sudo apt-get update && sudo apt-get dist-upgrade -y
sudo rpi-update

Next we are going to check for bootloader updates. We do this using the new rpi-eeprom utility. The following command will check for updates:

sudo rpi-eeprom-update -a

For a lot more information about the new rpi-eeprom bootloader utility make sure you check out my Raspberry Pi 4 Bootloader Guide.

If you have multiple SD cards or storage devices laying around it is a good idea to designate one of them as the “Official Raspbian Firmware Updater” card. Using this method you can periodically swap out the card and install the latest firmware updates to your Pi 4 and then switch right back to Ubuntu.

Preinstalled Image Download / Instructions

To download the precompiled image see the releases section located at https://github.com/TheRemote/Ubuntu-Server-raspi4-unofficial/releases

The file you are looking for on the releases page is ubuntu-18.04.4-preinstalled-server-arm64+raspi4.img.xz. Download this file and extract the .img file from inside. Use the free and awesome 7-zip if you are on Windows to extract the .img file.

Now burn the .img file using your favorite program. I use Win32DiskImager. Now insert your SD card / storage device into the Pi and start it up!

Username: ubuntu

Password: ubuntu

Upon logging in for the first time you will be required to change the default password to something else. Once you have done that log back in and you should be all set!

Updates

Using apt-get

First and foremost 99% of your updates will be coming from Ubuntu’s official repositories directly from apt as it would with any official image. The only things set on package hold (using apt-mark hold flash-kernel linux-raspi2 linux-image-raspi2 linux-headers-raspi2 linux-firmware-raspi2) to prevent them from overwriting the firmware already on the image. If you wish, you may apt-mark unhold those same packages and you will be 100% official Ubuntu. Your installation will probably immediately break if you do it now, but when the RPI 4 support is backported this is how you can change back to theirs.

Included Updater

I have also included an updater that will give you the latest kernel/firmware/modules/fixes that are included in each release. If Ubuntu’s 18.04.4 update servers get working firmware for the Raspberry Pi 4 I will change the update script to remove the apt-mark holds on the Raspberry Pi firmware package in apt and close the project down (leaving this here for people to learn from to hack an unsupported device into their own distros, or until I do it again on the next Pi release!)

Usage

If you have V18 or later of the image the updater is located at /home/Updater.sh. Type/paste:

sudo ./Updater.sh

If you have an older version of the image or need to manually update your Updater script, use the following commands:

wget https://raw.githubusercontent.com/TheRemote/Ubuntu-Server-raspi4-unofficial/master/Updater.sh
chmod +x Updater.sh
sudo ./Updater.sh

Updates to the kernel/firmware/fixes to common problems will be provided as long as there is interest.

Forcing Update

If you want to force the update (if you suspect/know something went wrong during an update, or you are troubleshooting, etc) use the following commands:

cd /home 
sudo rm /etc/imgrelease 
sudo ./Updater.sh

These commands remove a small file that contains the version of the image you have installed. This will cause the updater to allow you update again.

Install Full Ubuntu Desktop Version

To install the full version of Ubuntu Desktop use one of the following:

  • sudo apt-get update && sudo apt-get dist-upgrade -y && sudo apt-get install ubuntu-desktop -y
  • sudo apt-get update && sudo apt-get dist-upgrade -y && sudo apt-get install xubuntu-desktop -y
  • sudo apt-get update && sudo apt-get dist-upgrade -y && sudo apt-get install kubuntu-desktop -y

The xubuntu variant is lighter than the kubuntu variant but either one will need to download and install thousands of packages to complete the upgrade. This can obviously take quite a long time. How long it will take depends on your internet connection and the quality of your storage device.

Running this task overnight or when you have an errand to go run is definitely advised!

Performance

Storage

Beyond keeping your firmware and distribution up to date there is only one thing that sets apart one Ubuntu installation on a Pi from any other: your storage device. The difference between a low end to high end SD card can be a 2-3x performance, and the difference between a SD card and a solid state drive is a whole order of magnitude.

To help people know whether they have high performance storage I made the Raspberry Pi Storage Benchmark that will give you a performance score. Running the benchmark is really easy. Paste or type the following commands:

curl https://raw.githubusercontent.com/TheRemote/PiBenchmarks/master/Storage.sh | sudo bash

The storage benchmark will run several well known and respected benchmarks such as iozone and fio and calculate a score for your device.

Most importantly, to compare your score or if you want to just view other benchmark submissions check out the full results of all submissions in a searchable/sortable table at the Raspberry Pi Storage Benchmark Results Page.

Using USB Storage / Solid State Drive (SSD)

Right now the Pi 4 still lacks USB boot support. However, you can still do it by using the trick of having a SD card that you use as a bootloader only and have the rootfs on your USB storage. This is kind of a waste of a SD card but it’s definitely worth it as it allows you to hit those full sweet sweet USB 3.0 transfer speeds right now without waiting until the USB booting firmware update is released.

Using a solid state on the Ubuntu image is incredibly easy (even easier than Raspbian). Here’s the instructions:

  • Download the Desktop or Server image above and write it to your SD card
  • Navigate to the /boot drive on your SD card and open cmdline.txt
  • Change the part of the line that says root=/dev/mmcblk0p2 to root=/dev/sda2
  • Now burn the image again to your SSD
  • Plug in both the SSD and Micro SD and boot up the Pi

See my Raspberry Pi 4 USB Booting Guide for more information on USB booting / how this works / how to set it up.

Known Issues / Fixes

This section will be updated with known issues/fixes as people test the image and give feedback.

No display (HDMI)

If you have no display on your HDMI monitor you may need to toggle some options in /boot/config.txt. Put the SD card back in your computer and go to config.txt on the boot partition.

Here are some examples of good ones to try to get your display working:

#uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

#uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

#uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

#uncomment to force a HDMI mode rather than DVI. This can make audio work in DMT (computer monitor) modes
#hdmi_drive=2

#uncomment for composite PAL
#sdtv_mode=2

Which option or options may fix it for you is impossible to say. Everyone’s display is different so you may have to try a few times before you get it.

Kubuntu-Desktop display issues

If your windows are not drawing correctly in Kubuntu (missing window borders, black screens in windows, etc.) then you need to disable compositing.

Use the shortcut Alt + Shift + F12 to disable the compositor and everything will draw normally.  Now go into the Settings app and go to the “Compositor” section and uncheck “Enable compositor at startup” to prevent it from turning back on when you reboot.

This has been resolved in V16+.

Build Instructions

If you don’t want to use the precompiled binaries you can also build it yourself with the provided build script!

The build script is meant to be ran in a *throwaway* Ubuntu 18.04.4 Virtual Machine (VM). Here are the reasons you shouldn’t ignore this:

  • Absolutely no steps have been taken to make the process “secure” or “safe” for your main machine
  • It assumes the home directory is safe to build in (it’s not on a main system)
  • It installs hundreds of development packages that you only need to build the image (would bog down a main system)
  • It chroots into at least 4 different images during the build and chroots leak (causing instability/security concerns)
  • If things go wrong with the type of commands used in the script your system can get borked *real quick* (like instantly)

Now assuming you have your fresh throwaway VM ready download the build script:

cd ~
wget https://raw.githubusercontent.com/TheRemote/Ubuntu-Server-raspi4-unofficial/master/BuildPiKernel64bit.sh
chmod +x BuildPiKernel64bit.sh

Now is a good time to read through the build script to understand what it is doing. It will download several images and update them in a chroot and then extract the firmware. It then sets up all of the changes/fixes in the target image.

Once you feel you are ready to proceed run the build script with:

./BuildPiKernel64bit.sh

The script’s final output will be “ubuntu-18.04.4-preinstalled-server-arm64+raspi4.img” along with the xz compressed version and an updates.tar.xz file which is meant to bring a normal 18.04.4 installation up to date.

    Hi James,
    Since ubuntu 18.04 already have official support for RaspberryPi from Canonical, any idea how to merge your image with the official image?

  2. Avatar for louis

    Hi all,
    got a little loca difficulty.
    I gotta Pi4/4gb Samsung T5 500GB SSD and Mate desktop 1804.4
    After many false starts I still have not got it booting from SSD
    I’ve done the rpi-eeprom bit – that was straightforward but
    I’ve got Raspian on a 16GB SD
    it’s fully updated
    But I can’t navigate to the /boot drive koz iit is not clear to me where it is
    And I am assuming I was correct in flashing Mate to the SSD
    but how do I make it install from there?
    Ot should I install it like a fresh install through the PC?
    All I can see are a bunch of directories
    Someone pliz tell me what I am doing wrong

    James, will you be adding 20.04 pre-installed with a desktop? I ask because my wifi is broken. It only lets me connect with my pi in a gui’s browser(bad service, don’t ask). So using ubuntu server is not a viable option 🙁

    Any chance you ccould bundle the pack and put it up onto git for me pease?

    Anyone know a way to update raspbians firmware and eep via downloading files and adding them through an offline method? The damn os refuses to connect to my wifi and I’m stuck. I also do not have any linux os at the moment, to download them that way. Stuck with copy/paste files or burn an img.

    Curious as to how importnt is it and do I need to before using ubuntu?

    Put Ubuntu server 20.04 on sdcard
    Installed kubuntu-desktop & lightdm, but didn’t accept password.
    Installed ubuntu-desktop – working great.
    Switched to plasma also great now.

    install synaptic gnome-disk-utility ktorrent glabels net-tools firefox htop mc ranger libreoffice kmymoney nextloud-desktop ttf-mscorefonts-installer python3 spyder3 thunderbird eric
    snap install chromium
    bitwarden via firefox
    carnet in browser
    WOW! Big improvement. Better than Raspi-lite + kde-plasma-desktop.

    For any of you all having trouble with this set up NOT working or not allowing you to log in, use a DIFFERENT SSD HD controller or enclosure. I went round and round with this and would get to the log in screen and it wouldn’t accept the default username and password. I’d start over and then the process would bomb out with errors, I’d start over. I thought it was the SSD I was using, tried a different one, same results or errors. I finally used a different SSD controller (just a straight controller, no enclosure) and it finally worked as it should. Took me long enough to get there, but that’s the issue the RPI4 or the uBuntu install (not sure which??) is VERY picky about controllers and it’s enough to drive one crazy. HUGE THANK YOU to James for this, mad props bro!

    I’ve been testing many distros on my PI4, but found your Xubuntu the very best. Youtube runs smooth on Firefox, w/o lags, very good.
    But wifi is not connecting to my router, it keeps trying to authenticate indefinitely. But Raspbian does.

      This is the first time for me to use this img on raspberry pi. I used 18.04 desktop version. I got the similar problems on wifi the same as you.
      I’d been connected to my router since the first installed, but every time I stopped or modified the configuration. the wifi become not able to connect and kept pop-up password input window to me. But I’m sure I put the correct pw evrey time. Any solution so far?

        Elbert, i’ve found what is wrong, but not the final solution.
        I am in Brazil and after boot, wifi region changes to US (all alone).
        This command you can see wifi region: “iw reg get”
        In my case I have to set region to mine: “sudo iw reg set BR”
        I dont know where you are but try with your region.
        Both Xubuntu and Ubuntu have this issue, Raspbian is ok.
        I dont know how to fix it definitedly. “raspi-config” does not fix permanentely.
        Tell us if you find some solution.
        Good Look.

      To change definitively the Region edit /etc/default/crda and in last line write your Region.

      This works on Ubuntu and Xubuntu.

    Is there way to integrate video codec into the pre-built image? I found the video play via vlc or mpv is not fluent at all.

      Do you mean PI3???
      On my PI4 I play videos perfectly on vlc or youtube, very good!
      I think vlc has all codecs built-in.
      I think you have other problems.

    Although I really appreciate all the hard work for this. When installed on a Raspberry Pi B+ it is painfully slow. Just wanted to give a heads up to anyone wanting to try this on a B+. Thanks again!

    I seem to have a problem with APT. “apt list” only lists installed packages. I can list or install available packages. For example “sudo apt install mc” fails

    Hi, May I know why you created the pre compiled images.
    Why USB boot instructions are not working on Official ubuntu releases. eg cmdline.txt missing in office ubuntu release

    Silly question maybe – but has the kernel been compiled without multiarch support?

    After running dpkg –add-architecture armhf – I still can’t run any armhf / armv7 type precompiled binaries (although installing is fine).

    Is there a quick way to fix this – or would I need to compile a custom kernel?

    Hi James,

    I would like to know whether it is possible to merge Ubuntu server 18.04.4 + Docker Home Assistant on Raspberry Pi 4 + boot from SSD drive to one installation image of Ubuntu server 18.04.4.

    There are a lot of Home Assistant users all around the world and I am pretty sure that most of them would appreciate to have such a possibility.

    I have tried to install it based on the tutorial from other website
    https://www.juanmtech.com/set-up-hassio-in-docker-and-in-an-ubuntu-server/
    But there are a lot of problems with docker installation (install docker-ce for example) when I tried to apply in on Ubuntu server + raspberry pi4 + ssd boot drive.
    I tried the same tutorial on VirtualBox (PC) and there was not a problem.

    I suppose there differenece between repozitories of classic Ubuntu (server or desktop for PC) and Raspberry and that is the reason why I cannot install and enable a docker (docker-ce). And after that install and Home Assistant.
    Link here – https://www.home-assistant.io/hassio/

    That is why I see a big potential to have custom image of Ubuntu server 18.04.4 that fully supports Home Assistant docker installation.
    What is your opinion ?

    Does 2nd hdmi display work (dual monitor)?
    I have only been able to get mirrored display so far on other arm64 for pi4 images (ubuntu and debian).

    Great job !!
    However, when trying to login via SSH the first time (I’m using the Pi4 headless) it gives me an expired password warning and it should be changed.
    But before I can do anything it throws an “Authentication token manipulation error” and immediately disconnects.
    Is there a way to avoid/overcome this issue?
    I’m using a Windows client to login, so I can’t reach the Ext4 partition easily.

    First off thank you for your excellent work. I downloaded the Ubuntu server/desktop. I do not find the /home/Updater.sh program. I did find the Updater.sh on the Xubuntu download. * My question is do I update with the shell program just once and then use the normal Ubuntu software updater? Thank you again.

    Many thanks for the excellent job on this. After installing ubuntu-18.04.4-preinstalled-server-arm64+raspi4.img, I’m trying to find /boot/cmdline.txt, and it’s not in /boot. I do really need to add my SSH into the boot sequence. How can I do this?

      I’ve used the cmdline.txt in /boot/firmware and it seems to work. if anyone knows why it shouldn’t be used, please chime in!

    hi james! first, i want to say thanks for this image, its been a savior for me after hours of frustration of getting ubuntu on my pi4 works right.

    however, i found difficulty of installing realvnc amd teamviewer on this machine. after installation, it just not do anything.
    anyone has tried to install realvnc/teamviewer before?

    regards,
    ado
