I installed Enpass on Mint 19x. I did use Enpass on the same device but the HD was erased. What I meant by restoring from a local database I meant by restoring my own password backup file database...
Just tried on more time just now on a a new machine running Debian 9.... I followed instructions, installed enpass and it automatically prompted me to a password window.. almost as it already have a password database.....it crashed after I entered my password...
In the past after installing I had to "restore from backup".....no longer the case. Actually as I mentioned before, now it just crashes as I mentioned above.
Hope I'm making sense....
