App disabled after Ubuntu Snap updates and server reboots

[PaulNokel]

Hi,

when the Snap updated Nextcloud to 20.0.1 all the Group Folders where missing. The solution was easy, the App was just disabled. Today I rebooted the server to install pending updates and the same thing happened again. Digging in the logs I found the following message:

I was not able to find a similar issue, so the problem might be related to my specific setup? Has someone experienced something similar and found a solution?
