Is there way to integrate synaptic package manager with snapd (snap packages)? Either when compiling from source or a .conf file? If not what is a package manager that will integrate with snap packages, Ubuntu repos and cinnamon 3.0.7?
GNOME Software (also branded as Ubuntu Software) is the first, and so far only, app to support installing snap packages.
Synaptic is not receiving much development work at this time, but if someone did contribute a patch to add that feature, I'm sure it would be included if it worked.
