[BUG] Regression with `PUID` support in v4.0.6

[rpatterson]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The # transmission-daemon process is running as UID 911, not the UID specified in the PUID environment variable.

Expected Behavior

The # transmission-daemon process should run as the UID specified in the PUID environment variable.

Steps To Reproduce

1. Take a working compose project that specifies the PUID environment variable
2. Run it under v4.0.5, note that Transmission can write to files owned by the PUID
3. Run it under v4.0.6, note that Transmission can no longer write to files owned by the PUID

Container logs

I no longer have the logs, but it printed something like /config/settings.json: permission denied

[j0nnymoe]

We need to have the container start up logs, it'll show the set PUID/PGID.

Cannot reproduce, need logs.

Your output doesn't demonstrate what UID the abc user has. When I had the issue, it was 911, not the PUID I set.

Apologies, I don't have time at the moment for followup, especially since I can use image: "linuxserver/transmission:4.0.5" as a workaround. I think as a maintainer, however, you might want to be concerned about this and not close this out of hand. Because of how poorly behaved Transmissions is, this PUID regression meant all my /config/resume/*.resume files were rewritten with defaults which means I lost all my per-torrent downloadDir settings, added and done dates, etc.. This is a serious PITA to restore for my 3k torrents!

[Roxedus]

Without logs we cannot be sure the envs were set correctly, thus we do not have any workable info to confirm this is a bug. There was no change in how dropping permissions were handled in this image between .5 and .6.

abc@dfe0f4840ba9:/$ id
uid=1000(abc) gid=1000(users) groups=1000(users)
abc@dfe0f4840ba9:/$ echo "$PUID $PGID"
1000 1000
abc@dfe0f4840ba9:/$ ls -la /downloads/complete/
total 1155136
drwxr-xr-x 2 abc users       4096 Aug  6 18:25 .

-rw-rw-r-- 1 abc users 1182826496 Aug  6 18:25 archlinux-2024.08.01-x86_64.iso

Im fine with letting this wither away into the abyss, in the hopes that there's logs the next time someone potentially reports the same happening.

Hello! I tried docker compose with PUID & PGID=0 and without this env. The error persists regardless. It appeared today after the last image update transmission:latest.

Container:

`root@bf86e3806aa8:/# id
uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),11(floppy),20(dialout),26(tape),27(video)

Your id command is run as root, it will always say 0:0. Docker exec as the abc user

[TougeAI]

Downgrade to the previous release linuxserver/transmission:4.0.6-r0-ls248 and invalid PID errors go away.

[Roxedus]

I don't get these with 4.0.6-r0-ls249. As logs are missing from OP, I assume this issue is unrelated, open a new issue following the template.

[zwimer]

This happens for me as well with the new update (the restarting). Not the container, the container never dies, the transmission process seems to restart; the linuxserver logo does not reappear in the logs either.

[MorganMLGman]

I have the same issue. No changes in compose file. Watchtower pulled new image at 2AM and transmission died.

[MorganMLGman]

4.0.6-r0-ls248 and no tail: invalid PID '' with the same compose file.

[sstrang]

I pulled the latest image earlier today, and can confirm the same issue in my logs as MorganMLGman. Reverting to an earlier version has stopped the repeated crashing of the Transmission process within the container.

[Roxedus]

There is a issue in transmission, but not at all related to PUID support, none of the comments has proven that.
The PID errors are due to transmission dying, transmission/transmission#7035.

This issue has become a mess, as no one has opened a separate issue regarding the actual bug in transmission, when prompted to do so. I am therefore closing this issue, and hope someone can open a proper issue(logs and all) here regarding the PID, so it can be pinned.

Please do not comment on the most recent issue with logs and behavior that DO NOT mimic the issue in the slightest.
