Update from paperless-ngx 3.0.4 to 3.0.5 doesn't work

[metawops]

Today I tried to update my paperless-ngx installation from version 3.0.4 to 3.0.5 but got this error:

I visited the given URL but that contained old information from 2025.

My 3.0.4 installation is just a few days old and I just started with paperless, never had any version < 3 installed before.
My /opt/paperless looks like this:

What can I do? 😳
Any help much appreciated! 🙏

Whats inside the data folder? Why is this Created?

[metawops]

The log folder is empty.

The folder and the (empty) SQLite DB were apparently created by Django when I was experimenting with post-consume-scripts, using manage.py shell while PAPERLESS_DBENGINE=postgresql wasn't set. So this folder and the empty DB were created.

Totally useless now. I'll remove and test again!

Thanks so much for the hint to the wrongly existing data folder, @MickLesk! 👍👍
Update worked like a charm now! 🎉🍾🥳💃🕺
