Describe your issue

I tried to install paperless-ngx. It does not work. If I got it right from the logs, postgres 14 is needed. Installed is as standard version 13. How can I fix this? How can I upgrade to 14 and is there any kind of risk for my other applications?

For your help many thanks in advance!

You are running yunohost 12, which ships postgresql 15.
Check migrations : webadmin >tools>migrations
Are there pending migrations?

there is a topic in previous migrations:

  1. Migrate databases from PostgreSQL 13 to 15

I found these instructions:

I´m afraid, I need to do it in the same way.
There is no other way? Start migration again? Paperless was not installed yet.

I had no luck with migration re-run, see: Paperless doesn't start - #16 by jedie
