[Linux/Dietpi] Unable to connect to sabnzbd after 4.0.0 update

[chonger]

I have sabnzbd running as a service on my Raspberry Pi 4 running Dietpi. I updated sabnzbd to 4.0.0 version and now I can't access it on my network. I have confirmed in Dietpi that the sabnzbd service is running but when I try to access it via http://192.168.xx.xx:8080/sabnzbd/ I am unable to connect. I have radarr and sonarr also running on that Pi box and I'm able to access those services fine. Am I missing something?

[chonger]

Looks like the service isn't able to start. I've tried to get this to start multiple times manually using DietPi's service manager and I keep getting this. How do I get the service to start?

Running journalctl -u sabnzbd.service shows the syntax error below.

I have the same syntax error (Debian 4.19.269-1 (2022-12-20) x86_64 GNU/Linux). Cannot start SABnzbd after upgrading.

[sander]

See https://github.com/sabnzbd/sabnzbd/issu ... 1528314207

So: python3 version is ... ?

[tildajones]

From what I have read the walrus operator was introduced in Python 3.8.

Correct. See release notes: python 3.7 not supported anymore

[pauladkins]

After the update I can't connect either.

"can't connect" is logical if SABnzbd is NOT running at all. Check your python3 version: it must be python3.8 or higher.

[pauladkins]

SAB runs for a few seconds starts to d/l & then closes. I will check my python version. Thanks

That looks like something else. But ... start with the python3 version.

Mine also crashes once starting a download. Installed python 3.8.10 to force a upgrade, still happened. Trying a full server restart now to ensure the dependencies are working. If that fails, I'll downgrade back to 3.72 and try extract the logs.

Note, using the legacy/windows/standalone.

[Koos50]

Same here standalone version 32bit, after downgrading too 3.7.2 all good and it works again
