Sorry.
Because I want fix snap use old version.So if snap upgrade to 3.18.1 will too long time.Maybe I need use manual install.So I ask friend how to import database.Sorry.

Snaps are ALWAYS behind manual/docker etc.

Leave your manual install on 3.18.1 and wait for the snap to update to the same version, then migrate.

OK,I understood.Thanks a lot.
