[Solved] Missing module: cgi [Debian Bullseye]

Post by tcd »

Hi everyone,

I have a little problem to start sabnzb after upgrade from Debian Buster to Bullseye. After start follow message

Code: Select all

Not all required Python modules are available, please check requirements.txt
Missing module: cgi
I checked all requirements via

Code: Select all

python3 -m pip install -r requirements.txt -U
But there is no module cgi. Also there is no python3-cgi module. I tryed also to install sabnzbplus from Debian source for dependencies. But nothing helps.

How can I fix this problem?

PS: On Buster sabnzb runs very well with Version 3.4.2

cgi is part of The Python Standard Library, and thus a standard python install.

On a clean bullseye docker with only python3 installed, it's there:

Code: Select all

[email protected]:/# python3
Python 3.9.2 (default, Feb 28 2021, 17:03:44) 
[GCC 10.2.1 20210110] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cgi
>>> 

Code: Select all

[email protected]:/# find / -name cgi\* | grep python
/usr/lib/python3.9/cgi.py
/usr/lib/python3.9/cgitb.py
/usr/lib/python3.9/__pycache__/cgitb.cpython-39.pyc
/usr/lib/python3.9/__pycache__/cgi.cpython-39.pyc


So recheck your python3 install

Here almost the same output. I cannot show the output here, because I don´t have permission to post links. (Even marked as Code)

I tried a reinstall of python3 and all modules. The same result. The local sabnzb (from source) won´t start. The original Bullseyeversion runs well.

As sander mentioined, cgi is part of the python standard library and thus always installed with the python interpreter package.

Do you see better results if you call python3.9 directly (instead of 'python3')? Or in a fresh user account without any pip stuff or other modifications from prior to upgrading Debian?

This is a OS / Python problem. Not SABnzbd related. And out of my league. So I'll unsubsribe from this thread.

With help from a very friendly User from german Debianforum, I found the solution.

Via "strace" I saw, that sabnzbd try to use a python module inside of sabnzbd directory. (/usr/local/bin/sabnzbd/cherrypy). I don´t know why. But all other python modules normaly in /usr/local/lib... So, the cherrypy module try to find other modules in the same dir. Of course the script can´t find any other and stops working.

I delete the complete directory except the ini file and installed the original source from here. Now it´s working very well. ;D

strace is a nice tool.

Cool it's solved.


/usr/local/bin/sabnzbd/cherrypy is strange as "cherrypy" is not shipped by SABnzbd.
