OOWOW Ubuntu 26.04 LTS

Does anyone know when we can expect to have an Ubuntu 26.04 LTS image to flash via OOWOW?

Thank you.

There is a Ubuntu 26.04 test image for you to install via oowow online.

Note: This is a test version and many functions are not enabled.

Thank you for the image, but I prefer to wait for a stable release of Ubuntu 26.04 Server, possibly also running the latest release of the Linux kernel (7). I want the VIM4 I need to set it up to last for years to come.

請問 VIM4 “khadas-linux-7.0.y“ → 7.0 內核源碼什麼時候開放在 git 下載編譯阿 ?

Hello @Andy_Chen

你可以从这里获取：GitHub - numbqq/linux at khadas-linux-7.0.y · GitHub

Do you have an Ubuntu Server 26.04 image to try via OOWOW?

Hello @matteoguglielmi

No, but you can build from fenix yourself.

matteoguglielmi · July 27, 2026, 7:19am

git ls-remote https://github.com/khadas/linux.git | grep heads

There is no ‘7.0.y’ branch available yet.

Despite that, I could successfully build the following image:

vim4-ubuntu-26.04-server-linux-5.15-fenix-1.7.6-260727-emmc-develop.img.xz

which fails to boot with this error:

mmc_gpt_read: invalid GPT
fill_ept_by_gpt: invalid gpt
mmc_device_init()-1979: get partition table from dtb failed
_mmc_check_gpt: gpt is invalid and can't be repair

Hello @matteoguglielmi

Have you checked the SD-USB image ?

matteoguglielmi · July 28, 2026, 12:44pm

Yes, the following image works when flashed to the eMMC.

vim4-ubuntu-26.04-server-linux-5.15-fenix-1.7.6-260728-develop.img.xz

Hello @matteoguglielmi

Okay, you can use this image and we will check the eMMC image issue.

Hello,

Is there any progress in running the VIM4 on a more recent kernel and fixing the NFSd kernel panic?

I am currently stuck with 3x VIM4, having an unusable NFS server, and with such an old 5.X kernel that is causing me software development issues.

Please give us an update.

Please let us know if you have no solution in sight yet.

The kernel is too old with broken/unfixed services.

Sorry for the rant but have been waiting for so long and need to move on either because you help upgrading the OS on your devices or me buying non-khadas new SBCs.

Thank you.

EDIT:

This recent rolling image from Armbian (which is exactly what I was looking for: 7.X kernel + Ubuntu 26 server):

Armbian_26.11.0-trunk.47_Khadas-vim4_resolute_current_7.1.13_minimal.oowow.img.xz

seems to work on the VIM4 (power-up and shutdow work correctly and after the first boot I see clean dmsg and no failed services, which is encouraging).

I will test it much further and post back here again.
