Original GitHub issue: https://github.com/ciur/papermerge/issues/275

Originally assigned to: @ciur on GitHub.

Hello, I have installed Papermerge 1.5.5 via Docker (Compose). I use Traefik as a reverse proxy. In the papermerge.conf.py of the worker I entered the IMAP host, the username and the password (otherwise I ignored the rest of the email settings - BTW, here you should do some work in the documentation and at least write in possible values and example).

If I now create a searchable PDF with my document scanner and send it via email, the PDF arrives in Papermerge after a short time. If I still view the PDF via IMAP access, everything is fine. But in Papermerge every PDF is broken, i.e. I don't see any content of the PDF.

Is this an error configuration on my part or a bug?

I had the simular problem with docker and mounted volumes. Do you use mounted volumes for the docker container? Then you will need to set the right permissions on the mounted folders on your docker host.

the 3 mounted volumes have that permissions:

drwxr-xr-x 2 systemd-coredump root 4.0K Dec 29 05:52 redisdata

what should i change?

this is first a test environment, later i would like to change to a mysql database, if possible.

Hello HassanMullah,

I did the following:
Open an interactiv session in the papermerge container (docker exec -it container_id /bin/bash)
Then show the user id (id -u) It should be 1001 (www)

Exit the container session.

Then i change the owner of media_root zu 1001 (chown 1001 media_root/)
After restarting the container all new files where archived correctly and were visible.

I running the volumes at the moment with this permissions:

drwxr-xr-x 2 1001 0 3981312 Dez 28 12:30 broker_queue
drwxr-xr-x 4 1001 0 4096 Dez 21 13:38 media_root
drwx------ 19 999 0 4096 Dez 29 09:12 postgres_data

I'm not a big docker and linux crack, so there is maybe a better solution ;)

The file papermerge.conf.py.example helped me a lot.
