Bug#993233: squashfs-tools 4.5 are incompatible with snap 2.49-1+b5

[Tomas Jura]

Hi

The squashfs-tools 4.5 are incompatible with snap 2.49-1+b5
The problem is solved by this pull request 
https://github.com/snapcore/snapd/pull/10567

All snaps are not usable now. A new release of debian package is 
necessary soon.
