yes, everything is working fine on my Ubuntu laptop, except some snaps since I have activated parallel installation ![:slight_smile: :slight_smile:](https://forum.snapcraft.io/images/emoji/twitter/slight_smile.png?v=12)
Ubuntu: 20.04.1
New information:
if I “reinstall” a broken snap (remove
add
restore (data), it works again ![:muscle: :muscle:](https://forum.snapcraft.io/images/emoji/twitter/muscle.png?v=12)
Here is a broken snap, Chromium
Notice the start of this snap fails for another lib: libatk-1.0.so.0
