Happy New Year everyone! It’s only the 3rd and I already broke my new install.
After changing the UID/GID I cannot run toolbox or Podman anymore.
➜ ~ id
uid=1985(mihalyr) gid=1985(mihalyr) groups=1985(mihalyr),10(wheel) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
➜ ~ toolbox enter
Error: failed to get the Podman version
➜ ~ podman version
Error: creating tmpdir: mkdir /run/user/1000: permission denied
This is a fresh F37 Silverblue installed with the installer. I created the user with the first setup wizard with UID 1000 as usual. But I have old backups to restore and I use my custom UID/GID for my users to work simpler across systems. So, after finishing the basic setup and confirming it works, I went on to change the UID/GID from 1000 to 1985.
usermod -u 1985 mihalyr
groupmod -g 1985 mihalyr
find /home/mihalyr -user 1000 -exec chown mihalyr {} \;
find /home/mihalyr -group 1000 -exec chgrp mihalyr {} \;
Actually, I ended up running the find for all the mounts, just in case.
After this everything Just Works™. At least I thought, until I tried toolbox.
This is a very similar issue here which is closed without a solution that works for me: podman stop work after user ID change · Issue #15310 · containers/podman · GitHub
They suggest to run podman system reset
➜ ~ podman system reset
Error: creating tmpdir: mkdir /run/user/1000: permission denied
➜ ~ sudo podman system reset
[sudo] password for mihalyr:

A storage.conf file exists at /usr/share/containers/storage.conf
You should remove this file if you did not modify the configuration.
Then I tried to use the overlay to force this reset, but didn’t help:
➜ ~ sudo rpm-ostree usroverlay

All changes there will be discarded on reboot.

And after a restart, I’m back where I started again. I’m running out of ideas on how to fix this. Any help is appreciated.
