@jovimaco this is due to a known bug. In addition, there is also another, minor known bug. Both will get hopefully fixed in 2.55.3, but currently snapd release manager @mvo is very busy to fix the bug which has stopped 2.55.2 and so I cannot provide further information. Note also that next week is Easter week and many of my colleagues are on vacation. I will post here when there is something new to test.
