Essential modules are missing, downloading cannot start.

SABnzbd makes Usenet as simple and streamlined as possible by automating everything we can. All you have to do is add an .nzb. SABnzbd takes over from there, where it will be automatically downloaded, verified, repaired, extracted and filed away with zero human interaction.

Essential modules are missing, downloading cannot start.

Post by TheLid »

Hi

So something went wrong my SABnzbdplus, the web interface just stopped working some time ago and I just left it for a while until a new version of SABnzbdplus appeared in App Central.

I installed this and I can now get onto the web interface and set it up but now I can't download anything. I seem to be getting 5 errors.

ERROR 4 minutes ago Essential modules are missing, downloading cannot start.
ERROR 4 minutes ago unrar binary... NOT found
ERROR 4 minutes ago par2 binary... NOT found!
ERROR 4 minutes ago SABYenc module... NOT found! Expecting v4.0.0 - https://sabnzbd.org/sabyenc
ERROR 4 minutes ago [N/A] The command in build_command is undefined

Any ideas please?

I do know how to SSH onto the NAS if needed but I know next to nothing about Linus so please be easy on me:-)

Thanks

I got rid of the error for unrar and par2 by restarting sabnzbd.

/usr/local/AppCentral/sabnzbdplus/CONTROL/start-stop.sh stop
/usr/local/AppCentral/sabnzbdplus/CONTROL/start-stop.sh start

I still get the error for SABYenc module, hopefully the developer can help out soon.

Thanks

I assume you did that via SSH?

I have disabled the app in AppCentral and reenabled it. I also restarted the app via the web interface.

I assume that this would achieve the same result?

I did that via SSH and those 2 errors have now gone. Thanks.

So I'm in the same situation as you now.

I followed the instructions here

https://sabnzbd.org/wiki/installation/sabyenc.html

to try to upgrade sabyenc to version 4.0.0 but I got the message that the latest version is 3.3.6

So how do we get version 4.0.0?

This worked for me
python -m pip install --force-reinstall --ignore-installed --no-binary :all: sabyenc3

But I still have the same problem....

This error is occurring for me too as of the last couple of weeks:

Code: Select all

ERROR 2022-02-01 20:38 Essential modules are missing, downloading cannot start.
ERROR 2022-02-01 20:38 SABYenc module... NOT found! Expecting v4.0.0 - https://sabnzbd.org/sabyenc
When I try to install SABYenc with the following code, I get an error. I think the problem is that I am not referring to the correct Python installation. Any pointers on how to get SABYenc installed? Thanks!

Code: Select all

pip install sabyenc

I'm having the exact same problem, but I'm not as familiar with how to install these modules. Everything has been working fine for me up until a few days ago. Is there a way to point me in the right direction as a new user on Asustor?
