NZBGet won't start

[PP1979NL]

This mornig I noticed my MZBGet stopped working.
I tried to execute the package again, but immediately after that the package stops again.
When I show the log, it says nothing about any problem.

I have not updated anything or so.

I searched on this forum and found a threat with almost the same problem (#1608)
But the there mentioned options don't give the wanted result.
Below is the text copy pasted from the Putty SSH connection

Pls could someone help me out?

su: must be suid to work properly is because you should log in as root, not admin. Both accounts share the same password.

Then, the command /usr/local/nzbget/var/nzbget.log won't work: you'll see an error regardless of the account you're using.
Instead, use vi /usr/local/nzbget/var/nzbget.log, or tail /usr/local/nzbget/var/nzbget.log (that only shows latest entries). Alternatively, you could consider a graphical interface, such as WinSCP.

Lastly, if the logs don't show anything useful enter this: su - nzbget -c "PATH=/usr/local/nzbget/bin:${PATH} /usr/local/nzbget/bin/nzbget -c /usr/local/nzbget/var/nzbget.conf -D" and show the result.

Hi Dr-Bean,

Thx for the reply. Sorry for being such a big noob on this.
I will try WinSCP later on..

This is what I get when I try the things above. I'm doing something wrong but have no idea what.
thx in advance for helping me out.

The last command should all be on one line. Copy/paste this, and make sure it's executed as one command:

su - nzbget -c "PATH=/usr/local/nzbget/bin:${PATH} /usr/local/nzbget/bin/nzbget -c /usr/local/nzbget/var/nzbget.conf -D"

As a suggestion, it might be easier for you to uninstall and reinstall nzbget. That does mean you'll need to reconfigure it from scratch.

[PP1979NL]

Btw on your suggestion I used WinSCP and opened the logfile. It was 0Kb. There was nothing in it at all.
Is it possible to make a backup of the configuration before reinstalling NZBGet?

[Dr-Bean]

NZBget configuration is located at /usr/local/nzbget/var/nzbget.conf. You can make a backup, but I would suggest to not immediately use it: if your problem is caused by your configuration, then you're back where you started.

So my suggestion is to backup that file if you want, reinstall NZBget, and start with the default configuration where you can. Make sure permissions are correct (allow users group read/write access on the download directories), and see if NZBget is running correctly. You should be able to work it out from there.

[PP1979NL]

Again thx for your input.
I have created a group called "Media-accounts" I have added the users of NZBGet, Sonarr and CP to that group and gave it all the needed rights. If I reinstall Sonarr will the user be the same or is there a new userid created with the same name?
I have set those rights a very long time ago. Could you tell me where to find the file containing that user information?

[Dr-Bean]

I'm sorry, but you're on your own with that one, we don't provide support when our package users have been altered.

[PP1979NL]

No I have not changed your user. I have put your user in a group with all needed rights to create folders and so on. I did do the reinstallation and it is working fine now again. I tried to put the config file back and the installations seems to hold up. :-)
I only need to set the userrights correct so it can create folders again, that is why I asked if you knew where the file for that is being kept.

[PP1979NL]

I found out where I had t o do it. /etc/groups.
All working fine again. Thx al lot for your help and patience!
