A workaround I did was sudo docker exec --user 0 -ti pretalx pretalx init, but I hadn't yet verified whether it solves the problem

[rixx]

Happy to merge PRs fixing this problem! As the pretalx docker image is community maintained, I won't have time to look into this myself.

[Zaczero]

I was not able to reproduce the issue. Could you please share more details about your setup? Are you using docker/docker-compose? Do you use docker volumes? Did you follow the production instructions?

[d33tah]

@Zaczero I only cloned it and ran docker-compose up -d.

[rixx]

I was not able to reproduce the issue.

Weird, because I just set up pretalx-docker for the first time in probably five years, literally only ran docker compose up -d and docker exec -ti pretalx pretalx init as instructed by the README, and could reproduce the issue just fine.

Would be nice if somebody could either provide better setup instructions or add the --user 0 workaround to the README.

[lujoga]

The problem seems to be that currently there is no pre-built pretalx/standalone image with a /public directory owned by pretalxuser. This should be fixed as soon as an image based on the updated Dockerfile is released.

[rixx]

There is no new image being released, because the GitHub action for a release ran into a timeout after six hours of … not much happening (cf).

I'll re-run the job, but if that doesn't change anything, somebody will have to fix the build or people will just have to build the image locally.

[uebmaster]

Same issue for me.

Thanks in advance.

[turbotimon]

Have faced the same problem (ans still have some open). I made a PR

Happy to merge PRs fixing this problem! As the pretalx docker image is community maintained, I won't have time to look into this myself.

@rixx Happy to make a PR to hopefully imporve UX, as it took me hours to find that out.. Not sure to fix all the problems people facing in this issue but at least it give some hints! #60

(Btw, still facing some issues with pretalx ignoring static path and imho the main docu could also improved, but thats in an other issue in the main repo)

[rixx]

imho the main docu could also improved

pretalx is open source and happy for contributions. Apart from that, it's mostly developed (and documented, and run, …) by me on my own, and the documentation (as well as every other part of the project) being imperfect just comes with the fact that I have limited time and attention. Apologies that it took you hours to find out how to run pretalx – this is probably where I should remind people that there's also the offer of hosted pretalx and/or a support contract for immediate help with problems like that.
