MySQL Connect Issues

Using Ubuntu 20.04 (LXC VM)

Papermerge works fine with SQLite as the backend database but when changing the configuration to MySQL/MariaDB it doesn’t connect.

papermerge.conf.py DBTYPE = “mysql” DBUSER = “pm” DBHOST = “localhost” DBNAME = “pm” DBPORT = “3306” DBPASS = “pm”

Error when trying to migrate:

• I’ve tried running via localhost & an external MySQL database to confirm it wasn’t a specific issue with the MySQL installation.
• I’ve confirmed being able to access both databases/tables with the credentials with mysql client via CLI

Any help would be greatly appreciated!

I tried with Postgres and it worked fine. Can’t wait for the MySQL fix.

I see in provided error messages that Papermerge thinks it deals with PostgreSQL database. It looks like it ignores DBTYPE = "mysql" configuration.

It is definitely not an SSL issue.

Thank you for reporting this issue!
