Install bubblewrap by default to make use of MAT2's sandboxing

Whonix should install bubblewrap by default. MAT2 uses bubblewrap for sandboxing and is automatically enabled if it is installed.

This currently won’t work though due to a bug (Whonix uses hidepid).


Will having the on fixed version installed break MAT2 startup? If not then we can incldue it.

Yes, it likely will.

I’m not saying to include bubblewrap immediately. It can be included after the bug is fixed.

I’ve submitted a pull request to bubblewrap that should fix the MAT2 issue.

It might take a while before it gets merged and then a longer while before it’s in Debian.
