Issue While installing snaps

Whilst trying to install snaps I get this error:
error: cannot communicate with server: Post http://localhost/v2/snaps/castersoundboard: dial unix /run/snapd.socket: connect: connection refused
What should I do?
Output of version is this:
snap 2.42.1+18.04
snapd unavailable
series -
Please help, thanks

I suspect your snapd is currently upgrading itself. The current released version is 2.45 so you’re running an older install at the moment. Give it a few minutes and then try again.
