Snap broken in Fedora 31

Cubevoid · December 11, 2019, 10:31pm

Hello all,
I am not sure how, but it seems like all of my snap packages have stopped working in Fedora 31. Running the snap command gives me the error: error: cannot communicate with server: Post http://localhost/v2/apps: dial unix /run/snapd.socket: connect: no such file or directory.
The apps I had installed with snap no longer work, it looks like the icons have disappeared from the GNOME desktop and I cannot launch them anymore. I tried downgrading snapd using sudo dnf downgrade snap but that also gives me an error.

Using systemctl start snapd.service gives an error too: A dependency job for snapd.service failed. See 'journalctl -xe' for details.

I have no idea how this happened! Thank you for any help!

Edit: dnf reinstall snapd also gives an error

I uninstalled snap, and now I am not even able to install it!

I never seem to have a good experience with snap. Always stuck with flatpak instead. I suppose you’re not using it because you need snap?

Cubevoid · December 11, 2019, 10:47pm

I actually have both installed, since there are apps on both snap and flatpak that are not on the other. I do prefer flatpak, but I have never had issues with snap before.
