Essential modules are missing, downloading cannot start.
SABCTools disabled: no correct version found! (Found v7.1.2, expecting v8.1.0)

I've looked through the forum and found some instances of this problem over the years. However, I haven't found a solution to my specific problem. I'm running ubuntu 22.04 and I've had sabnzbdplus running for 6 months. I've been maintaining OS patching weekly. I just upgraded the OS and now sabnzbdplus no longer downloads giving me the two errors above. I've tried looking for this version 7.1.2 the error message gave me. I've tried as my login, the sabnzbd service account, and the root account:

myself@myhost:~$ sudo su - sabnzbd
$ python3 -c 'import sabctools; print(sabctools.__path__)'
['/usr/local/lib/python3.10/dist-packages/sabctools']
$ python3
Python 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sabctools
>>> sabctools.version
'8.1.0'
>>> sabctools.__path__
['/usr/local/lib/python3.10/dist-packages/sabctools']
>>>
$ exit
myself@myhost:~$ sudo su -

>>> import sabctools
>>> sabctools.version

>>>
root@myhost:~# exit

myself@myhost:~$ python3

>>> import sabctools
>>> sabctools.version
'8.1.0'
>>> sabctools.__path__
['/usr/local/lib/python3.10/dist-packages/sabctools']
>>>

Any help would be appreciated.

Note to self: instead of just "SABCTools disabled: no correct version found! (Found v7.1.2, expecting v8.1.0)", SABnzbd should print the sabctools.__path__

Jim:
* no python-venv involved?
* no different python version?
* no docker, snap, etc?

Very ugly brute force method to find sabctools stuff;

Code: Select all

sudo find / | grep -i sabctools | grep -vi docker

Or even lazier:

Code: Select all

sander@haring1:~$ sudo find / | grep -i sabctools | grep -vi docker | grep -ie dist-info$
/home/sander/my-python3-venv/lib/python3.8/site-packages/sabctools-7.1.0.dist-info
/home/sander/.local/lib/python3.8/site-packages/sabctools-8.1.0.dist-info

So I have sabctools 7.1.0 inside a venv

No python-venv, different python version, docker, snap, etc. I'm old and didn't want to learn yet another abstraction layer.

Here's the output from the global find. It still only shows version 8.1.0.
(I had to truncate some of the output because the forum editor kept telling me I wasn't allowed to post links yet.)

My guess is that the sabctools 7.1.2 is in /usr/local/lib/python3.10/dist-packages/sabctools/ or maybe in /usr/lib/python3/dist-packages/sabctools/

There are clever tools to find that out, but I'm not good at them.

Code: Select all

sander@haring1:~$ dpkg -S /usr/lib/python3/dist-packages/sabctools/sabctools.cpython-38-x86_64-linux-gnu.so

python3-sabctools: /usr/lib/python3/dist-packages/sabctools/sabctools.cpython-38-x86_64-linux-gnu.so

and

Code: Select all

sander@haring1:~$ apt policy python3-sabctools
python3-sabctools:
  Installed: 8.1.0-0ubuntu1~jcfp1~20.04
  Candidate: 8.1.0-0ubuntu1~jcfp1~20.04
  Version table:
 *** 8.1.0-0ubuntu1~jcfp1~20.04 500
        500 http://ppa.launchpad.net/jcfp/ppa/ubuntu focal/main amd64 Packages
        100 /var/lib/dpkg/status

A brute force method to solve it, is uninstalling python3-sabctools a few times, and then verify there is no python module sabctools anymore.

Oh, and if you installed sabctools via pip, then also uninstall via pip.

Thanks for your help troubleshooting this. I wasn't able to resolve the issue with the 7.1.2 version. I ended up building a new server and installing sabnzbdplus again.
