[BUG] Plugin is not supported for all default plugins

[lordbah]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

qbt v5.2.3. Search returns no results. Search plugins button brings up an empty list of plugins. Check for updates, or install new plugin, have no visual feedback. Enabling the execution log I can see:

Found Python executable. Name: "/usr/bin/python". Version: "3.14.7"
Plugin "eztv" is outdated, updating to version 1.23
Plugin eztv is not supported.

for all default plugins. Any way to see more details than "is not supported"?

Expected Behavior

Search should work. Installing search plugins, they should then be found.

Steps To Reproduce

Start the container on Synology, connect to it from your web browser, Search tab, Search plugins, Check for updates.

I no longer know whether Python 3.14.7 was installed prior to my adding it (from a bash terminal opened in the container), but it's there now, and I see no evidence of any other version of Python. And qbt logs that it finds it. So I'm not seeing how missing python can be an issue. I wasn't able to figure out how to 'apk add' any other version of Python to experiment with.

Based on web posts I did delete the nova3 directory and restart. It was recreated.

I don't think that this is compatable yet with python 3.14 (ie python 3.14 introduced a breaking change?). Can you try to downgrade to 3.11 or 3.12 to see if that helps? apk update && apk add --upgrade python3 py3-pip
then stop qbittorrent and delete all nova3 directories
and then restart qbittorrent and reinstall the plugins and that should fix it until they support 3.14. qbittorrent/qBittorrent#21445

[lordbah]

Hmm. I don't know why that command would install 3.11 or 3.12 instead of 3.14.7. But I guess I can try it.

[lordbah]

Yeah, even after removing (apk del) python3, running that command just reinstalls 3.14.7. I did more searching and came up with something else to try but it didn't work either.

root@f955a2c7f34d:/# apk add python3=~3.12                                       
ERROR: unable to select packages:                                                
  python3-3.14.7-r1:                                                             
    breaks: world[python3~3.12]

Even after 3.14.7 has been removed, something in the package system seems to know that 3.14.7 is the version that we absolutely have to use and refuses to install an older version :-(

[upmcplanetracker]

Ugh. Let me think on this and see if there is a way around it. Looks like it's been an issue for years. Wonder if a q BitTorrent subreddit or something similar on reddit would have a solution.

You can't downgrade python to 3.12 as this image is based on Alpine 3.24 and the repo for that OS version does not have a package for python 3.12 (it's too old).

You need to figure out which plugin is causing the issue, then either remove it or reach out to the plugin author and ask them to update it.

I no longer know whether Python 3.14.7 was installed prior to my adding it (from a bash terminal opened in the container), but it's there now, and I see no evidence of any other version of Python. And qbt logs that it finds it. So I'm not seeing how missing python can be an issue.

Python is included in this image: https://github.com/linuxserver/docker-qbittorrent/blob/master/package_versions.txt#L70

[upmcplanetracker]

What about pulling a non lsio version of q BitTorrent like
https://github.com/hotio/qbittorrent. Maybe it's something in the lsio dependency packaging? May be worth a try. Seems low risk. Probably not high reward but just a single line change pointing to a different repo.

[upmcplanetracker]

I'm 99% sure it's the alpine version in LSIO as @aptalca said. so I think the choices are iether a non alpine version:
image: hotio/qbittorrent:latest
or downgrade qbittorrent to something like 5.0.0 which still uses older version of python.
tbh i'd just switch to the hotio version if it works.

[aptalca]

Or, you know, you can do what I suggested and get to the bottom of it so it's fixed for everyone instead of you putting a band-aid on it. That's why we have open source.

[lordbah]

You need to figure out which plugin is causing the issue, then either remove it or reach out to the plugin author and ask them to update it.

I don't have any plugins installed. The execution log complains about all of the default ones.

[aptalca]

Then you can report to qbittorrent devs. For reference, they state python compatibility with versions equal to or higher than 3.13.0, so technically 3.12 is not even supported
