Ubuntu 20.04 is here for the CM5! There are two images because the ubiquity installer fails on the CM5, the CM4 image will run on the CM5 but the installer will fail though. So I’ve made a image that is preinstalled and works with the CM5. Make sure to make a new user/pass if using that image!
Let me know if something doesn’t work, Ubuntu makes things difficult and their SBC images are definitely second class to them. Like WiFi for the CMs is broke out of the box from Ubuntu.
If you are on a CM4 you can just download the CM4 image and go though the installer.
Ubuntu is a Linux distribution derived from Debian and composed mostly of free and open-source software.
Features: ClockworkPi-Bookworm-6.12.y
Sane charging defaults applied.
External WiFi antenna already set in config.txt.
linux-headers included with kernel
Works with both DevTerm CM4/5 and uConsole CM3/4/5.
Auto-expanding file system
On first boot system will boot expand FS then reboot.
I have added a few working/testing images and kernels with the *.deb files to install in the mega folder if you want for different OSs.
Google Drive link for the main image if Mega doesn’t work for you.
Here’s my Github with the rpi-6.12.y branch if you’d like to compile yourself. All the ClockworkPi drivers are pre-marked to compile in bcm2711_defconfig or bcm2712_defconfig. Also the APT repo with kernels and hardware scripts for ClockworkPi devices
I was going to ask you Rex to do this one as its my favourite Linux distro thank you brother. Now all i need is Batocera if you can get that running Uconsole.
Awesome work @Rex! I’m using it right now and it feels very snappy on the CM4. Haven’t run into any problems so far, installation was a breeze. Thank you so much!
I’m having the same issue with this Ubuntu image that was reported for initramfs. I looked at this solution:
However, my initramfs.conf file already has the ‘MODULES=most’ line. I couldn’t figure out how to solve it. The kernel seems to have been updated, but the error persists after attempting another ‘apt upgrade’. I just restarted my uConsole and it booted up correctly though.
EDIT: the error message is not the same as in the Bookworm image, so here’s the error for Ubuntu:

Did you force update the kernel? I thought I mark it on hold, I’ll have to go back and check.
The only systems that can get automatic kernel updates are the Debian builds. Ubuntu has deviated far enough away from Debian that my kernel package can’t be use to update it.
I’m looking through my command history and I seem to have done ‘apt upgrade’ only. Would it help to manually downgrade the clockworkpi-kernel package using the .deb file for the previous version?
I’ve imaged an SD card with the Ubuntu Preinstalled Image and it doesn’t seem to be happy. Booting the uConsole results in a black screen. If I plug a display in, I can see that the bootloader on the pi is first unhappy with the config.txt, it needs me to add os_check=0 in order to boot. After I shut down and edit that file and reboot, the bootloader seems to just loop, claiming FAT read errors, but doesn’t complain about the config.txt anymore. It seems like there probably isn’t a FAT read error if it can validate the config.txt, but I’m a little out of my depth.
Is this a known issue? Or maybe I’m doing something wrong, getting the image onto the SD card with rufus and now trying rpi imager.
ETA: After lots of restarting and waiting it seems like the ubuntu image is booting… I’m not sure why the pi thinks the SD card can’t be read at first. I guess maybe it does the same thing with the CM4 and I just haven’t ever been impatient enough to notice?
ETA2: Seems stabler now, after first full boot it seems like it “figured out” how to boot from the SD card. All of this is such a black box to me
