How to install JDownloader2 in 2024?

TrueNAS General

There does not appear to be a JDownloader2 app by default. Many sources on the Internet however claim that it can easily be installed by adding a catalog called “TrueCharts”, for example as described here: TrueNAS Scale: Adding TrueCharts Apps Catalog - Tech Addressed

Unfortunately this does not seem to work (anymore?) and instead of manually creating my own JDownloader container, I would like to ask if anyone could give me a hint on how to install JDownlaoder2 from the chart: jdownloader2 | TrueCharts Charts

Truecharts deleted their Truenas Scale repo months ago. If you want to use their apps, you need to use their linux distro that’s build around their kube/helm environment. That would need either baremetal or a VM.

But pretty much all the truecharts plus iX official/community apps are just based on docker images created by other people. TC is probably based on GitHub - jlesage/docker-jdownloader-2: Docker container for JDownloader 2

Which can be installed in Truenas Scale as a custom app or through Jailmaker sandbox.

Set user/group, bind/hostpath mounts for config/data and ports. Looks pretty straightforward.

The next Scale release will be moving away from helm/kubernetes to docker(compose). Any iX official/community & custom apps will be migrated. Truecharts apps will not.

I see, thanks for the information. Creating a custom app surly seems like the easiest way to go, but it comes of course with a big disadvantage: I have to maintain it - no automatic updates, right?

Can you tell me more about why TrueNAS is moving away from helm to docker-compose?

Custom Apps configured via the TrueNAS UI use the same update tracking as train apps. If the docker image has an updated version available upstream, TrueNAS will alert and allow you to upgrade via the UI.

I checked with Docker Hub and jaymoulin/jdownloader appears to be the most widely used one by far with 50M weekly downloads, so I went with that and set all the options that it requires, but when it starts, it just spams errors and never becomes available.

Any ideas why it’s not working?

Here is my Config btw:

Did you follow the directions for docker or kubernetes install? Even though you’re installing a docker app, it’s still being ingested into Scale’s kubernetes environment.

Then again, first line in the log shows a probable permission issue: 2024-09-21T05:46:04.168478803-07:00 sed: can’t create temp file '/opt/JDownloader/app/cfg/

Don’t know why, but why not try the image instead (already suggested by Craig_L)? I’m using it too, literally 1 min to config and start downloading things

With that image it actually works just fine. But it has a big downside: It doesn’t run headless, it actually runs the GUI and a VNC server to access it which of course is way more intense on resources than the other image would be because that other image runs JDownlaoder headless in the background only exposing the MyJDownloader API port.

So if anyone has ideas on how to get this to work, I’m still very much interested. :slightly_smiling_face:

I tried it two ways:

  • Enabled Configure Container User and Group ID - userID set to 1001, group set to 100
  • Disabled Configure Container User and Group ID

So I’m not really sure what could have caused this. 1001:100 is what was suggested on the docker hub page and I’d assume if I don’t set any id it will default to root. Seems odd that it would still be lacking permission.

Clear, didn’t think about that. Perfectly legit!

You should probably check what user Is 1001 in your system, and in case adjust ACL on datasets

Did you - or anyone else - find a solution?
I followed your steps and ended with the same issues.
