Not as bad anymore, but:

https://openqa.opensuse.org/tests/2236916#step/zypper_in/26

Every now and then I see the cleanup 'timing out' (not the first case I see like this)

zypper has 90 seconds to uninstall 9 packages that total to 63 Bytes. That should be more than sufficient.
Looking at the video it seems that zypper in not just slow and eventually running into a timeout but it seems to hang up at that point. So I would consider that as another product bug.
Sadly the zypper_in test doesn't upload the zypper.log so I will create a PR to do this so that developers can look at it.

The only useful entries from journal are these - I wonder why every entry is listed twice, though:

This should allow gathering some logs required for a proper bug report if it happens again.
