errors using snap installed programs

[lik...@gmx.de]

Hi!

I've used this instructions to install 2 programs using snap:
https://github.com/QubesOS/qubes-issues/issues/2766

Unfortunatelly, it happens on a regulary basis (weekly), that starting these apps results in the following error:
[user@b ~]$ slack
internal error, please report: running "slack" failed: cannot find installed snap "slack" at revision 17: missing file /var/lib/snapd/snap/slack/17/meta/snap.yaml
[user@b ~]$ snap slack
error: unknown command "slack", see 'snap help'.

I know that there's a fix in testing for classic confinments:
https://github.com/QubesOS/qubes-issues/issues/4798

But the same happens also with non-classic confinments.

The workaround is to re-install the snap programs. Unfortunatelly, with this you lose all settings of the progs.

Any suggestions or ideas?

Best, Pete
