System locked over the weekend - no access now

Hey everything was working great Friday… I just tried to get on via web and got page unavailable.
When I try to logon to console I see this:
Is there anything I can do to fix it?
Im pretty new to Linux and nextcloud, it was installed via the snap method.

I fixed it …somehow the UUID got messed up.
To fix it I had to boot using a live cd and enter the correct uuid for /dev/sda1.
rebooted and everything came right up.
