Arch Linux User Repository

The command listed in https://aur.archlinux.org/packages/nzbhydra2?O=10#comment-887324 doesn't work without further modifications because systemd doesn't expand variables in the Environment directive. As such, starting the service fails because the sh command can't be found. A possible workaround is to hardcode the path, i.e. Environment=PATH="/usr/lib/jvm/java-17-openjdk/bin:/usr/bin"

With the update to version 5, nzbhydra2 now requires java 17, so you'll have to make sure that nzbhydra2 is run with java 17: https://aur.archlinux.org/packages/nzbhydra2?O=10#comment-887324
This is only required for running, the package should build fine in any case.

Furthermore, while nzbhydra2 now also provides binaries for windows and linux (which are apparently built using GraalVM), this package will continue to build the generic jar, as it doesn't seem to be possible to build the binaries with OpenJDK and GraaVM is only available in the AUR.

The Java dependencies according to the upstream URL:

"You need Java Runtime Environment or OpenJDK (both (>=8u101 but it won't work with 9.x or higher)."

i.e. you kinda need to use 8.

Fixed, but I didn't bump the package version.

I'm getting validation failure:-

Validating source files with sha256sums... nzbhydra2-1.4.7-linux.zip ... ?[0m ?[91mPassed nzbhydra2wrapper.py ... FAILED

It does take a good 30s for mine to start up. :)

It's working now. I think I was too hasty.

I have been going over the journal log and the logs from nzbhydra2, but I am unable to find anything useful.

I can also locate nzbhydra2 running using "ps aux", and if I greb the PID and check "ss", the PID nzbhydra2 is running, but isn't listening on port "5076", rather on "99525", but it's not possible to connect to that.

# ps aux|grep nzbhyd

I shortned the output of the systemd status, it looks like this:

It should just work, but obviously isn't. Your sudo systemctl status nzbhydra2 doesn't look good to me either. Try sudo journalctl -xa -u nzbhydra2 and see if you see anything obvious.

Mine looks like:

$ sudo systemctl status nzbhydra2

Ok, thanks.

I have installed the package, and it is up and running (not enabled yet):

● nzbhydra2.service - NZBHydra2 Daemon
   Loaded: loaded (/usr/lib/systemd/system/nzbhydra2.service; disabled; vendor preset: disabled)
   Active: active (running) since Tue 2018-02-27 19:45:30 CET; 2min 11s ago

However, I cannot connect and a "ss" doesn't show it listening on port 5076 or any other port.

Is there something specielt that needs to be fixed first?

It is just a python wrapper. If desired, you can use an override to point at the native launcher. But this .py wrapper allows the package to be used on various platforms while the native launcher is only x86_64 or something.

If you want to do that, just...

sudo systemctl edit nzbhydra2 to add an override.conf, inside put...

[Service]
ExecStart=
ExecStart=/usr/lib/nzbhydra2/nzbhydra2 --nobrowser --datafolder /var/lib/nzbhydra2

I'm not quite sure whats supposed to be there as I haven't used nzbhydra before, but this one runs using Python and not Java?

ExecStart=/usr/bin/python2 /usr/lib/nzbhydra2/nzbhydra2wrapper.py

Haven't the service files been updated perhaps?
