[lxc-users] "error: LXD still not running after 5 minutes" - failed lxd.migrate - how to recover?

[Tomasz Chmielewski]

I've tried to migrate from deb to snap on Ubuntu 18.04.

Unfortunately, lxd.migrate failed with "error: LXD still not running 
after 5 minutes":

root at b1 ~ # lxd.migrate
=> Connecting to source server
=> Connecting to destination server
=> Running sanity checks

=== Source server
LXD version: 3.0.1
LXD PID: 2656
Resources:
   Containers: 6
   Images: 4
   Networks: 1
   Storage pools: 1

=== Destination server
LXD version: 3.3
LXD PID: 12791
Resources:
   Containers: 0
   Images: 0
   Networks: 0
   Storage pools: 0

The migration process will shut down all your containers then move your 
data to the destination LXD.
Once the data is moved, the destination LXD will start and apply any 
needed updates.
And finally your containers will be brought back to their previous 
state, completing the migration.

WARNING: /var/lib/lxd is a mountpoint. You will need to update that 
mount location after the migration.

Are you ready to proceed (yes/no) [default=no]? yes

error: Unable to connect to the source LXD: Get http://unix.socket/1.0: 
dial unix /var/lib/lxd/unix.socket: connect: no such file or directory

Not sure how to recover now? The containers seem intact in /var/lib/lxd/
