Thank you, this is a known issue with ubuntu 24.04, because there's already a UID=1000 before the WSL user is created, so the WSL user gets a different UID, which breaks wslg's expectation and leads to errors like the one you're seeing.

We've contacted the distribution maintainer to see if the UID can be fixed from their end

[salcinad]

Seems there is an default "ubuntu" user with Ubuntu-24.04 with id 1000, user created with installation have id 1002.
$ id 1000 uid=1000(ubuntu) gid=1001(ubuntu) groups=1001(ubuntu),4(adm),24(cdrom),27(sudo),30(dip),1000(lxd)

if i switch to that user i could run podman info, but this is not expected

$ sudo -i
# su - ubuntu
$ podman info

As a workaround you can install Ubuntu not from the Microsoft Store, but via wsl --import and get the image archive from here: https://cloud-images.ubuntu.com/wsl/

This way there is no prompt for creation of a new user. Note that things like Windows Terminal profile won't be added automatically.

This might be why I have a command entry in my /etc/wsl.conf

[boot]
systemd=true
command = mount --make-rshared /

[salcinad]

@Stelminator that will fix the problem/message with "WARN[0000] "/" is not a shared mount" but not the real issue which we have, and thus that there is already user in rootfs image (at lease in 20240508 release from the link which @trallnag posted). And thus when the installer prompts for User creation the new user gets id 1002 and can not execute the "podman info" command as seen in first post.

@OneBlue any replay from distribution maintainer?

[akinomyoga]

I think this is also related to #10473, #10498, and #9689.

[SirMishaa]

Would be interested to have news for this ? I've just installed new Ubuntu 24.04 from scratch and I got issue like that for other tools :(

[zohaibhassan156]

I beleive its resolved in latest version. you will need to update wsl and reinstall ubuntu24

wsl --update --pre-release
wsl --install

[tusharsnx]

I updated WSL to 2.3.21 and re-installed Ubuntu-24.04 and I still have the issue. UID 1000 is preallocated to the ubuntu user.

I updated WSL to 2.3.21 and re-installed Ubuntu-24.04 and I still have the issue. UID 1000 is preallocated to the ubuntu user.

You might have an old image.

I just imported noble/20240917, and it doesn't have the pre-allocated user; I could not quickly find a changelog mentioning it.
