OBS last builds failed on Fedora3x and some Debians

Hi everyone,

recently some builds (previously successfully built) started to fail:

It’s on Fedora38 Fedora39 for all architectures with a message like

[   57s] now finalizing build dir...
[   57s] SIOCSIFADDR: File exists
[   57s] su: cannot open session: Permission denied
[   57s] Error: TOPDIR empty
[   57s] ### VM INTERACTION START ###
[   57s] Failed to write wtmp record, ignoring: Read-only file system
[   57s] Failed to write utmp record: Read-only file system
[   57s] Powering off.
[   57s] [   48.070220][ T5451] reboot: Power down
[   57s] ### VM INTERACTION END ###

and on Debian (and derived distros) for armv7l with complains like:

unresolvable: missing pre/vminstalls: kernel-obs-build 

or

The repository setup is broken, build or publish not possible

Are they not supported now?
