Hi @DrVanSteiner, thank you for opening the issue.

Please don't use image tagged with "latest".

The docker image tagged with "latest" is pulled from master branch which is development branch. Please use image tagged with 1.4.5 instead.

I encountered the same error with the 1.4.5 tag. Following the documentation:

I cloned the repo locally
Entered the 1.4 docker folder cd docker/1.4 which used the image image: eugenci/papermerge:1.4.5
Changed the external port to 8001 (due to port conflict)
Issued docker-compose up -d

The webapp homepage shows a 500 Internal server error:

Internal Server Error

Please contact the server administrator at [no address given] to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.

The log:

I've also tried to checkout the git commit tag 1.4.4 and launch the docker-compose file from there obtaining an altogether different issue which I suppose isn't worth mentioning as I think it is better to focus on the latest release.

The problem was because I included "a whitespace" after comment in startup script - it considered that "whitespace" as entry point.
Lesson learned: no (white)spaces after backslash character :)
