When I restart my Ubuntu 18.04 system, it suddenly crashes and shows a long list of
[FAILED] messages as shown above, for example:
[FAILED] Failed to mount Mount unit for gtk-common-themes, revision 1198 See 'systemctl status "snap-gtk\\x2dcommon\\x2dthemes-1198.mount"' for details
and other mount errors like
[FAILED] Failed to mount FUSE Control File System
What could be the problem here, and how can I fix it?
