Some time ago I uninstalled snap, and probably messed things up cause now I can't install it back. When I try to run sudo apt install snapd
this error appears:
Package snapd is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'snapd' has no installation candidate
My system specs:

What should I do?
Ps. I tried:
sudo apt-get purge snapd
sudo apt-get install snapd
didn't work.
