After upgrading my Ubuntu to 20.04 , lxd didn’t start so I removed two files from /…/global and now ok
And now I can see containers list but two of them starts and two not
One which doesn’t start:

You mentioned having to do some database mangling to get things online, any idea what caused the database issue in the first place?
What dou You mean?
I’ve looked for solution in internet so sth happend after:
snap remove lxd
snap install lxd
snap save
snap restore
How did you perform the 20.04 upgrade? did you use do-release-upgrade ?
Yes, I used do-release-upgrade and it freeze on one of packets or it seemed to me be frozen
So I’ve restarted computer and finished upgrade manually using dpkg and apt
What do you have in ls -lh /var/lib/snapd/snapshots/?
Running snap remove lxd may have caused considerable damage, effectively wiping those containers, but maybe you’re lucky and there’s a usable snapshot through snapd.
One of your two containers also appears to have a snapshot, if that’s reasonably recent, then you can at least restore it to that state.
