Description Ian 2021-10-15 16:54:58 UTC
Description of problem:

Trying to use the debian_support python module this package provides gives an error (see repro below). If you uninstall this package and instead install python-debian via pip it works ok.

Version-Release number of selected component (if applicable):

0.1.36

How reproducible:

100% on F33/4/5.

Steps to Reproduce:

$ sudo dnf install -y python-debian
$ echo "import debian.debian_support" | python

Actual results:

```
  File "/usr/lib/python3.9/site-packages/debian/debian_support.py", line 46, in <module>
    apt_pkg.init()
apt_pkg.Error: W:Unable to read /etc/apt/apt.conf.d/ - DirectoryExists (2: No such file or directory), E:Unable to determine a suitable packaging system type
```

Expected results:

No error.

Additional info:

As I say if you uninstall via dnf then reinstall from pip python-debian works ok:

$ sudo dnf remove python-debian
$ pip install python-debian
$ echo "import debian.debian_support" | python

Gives no error.

Comment 1 Miroslav Suchý 2021-10-19 17:10:50 UTC
This actually comes from 
   import apt_pkg
   apt_pkg.init()
so switching components.

The reproducer should be:

$ python3
import apt_pkg   
apt_pkg.init()


But one question anyway:

> sudo dnf install -y python-debian

There is no python-debian. I assume typo and "python3-debian"

Comment 2 Miroslav Suchý 2021-10-19 17:13:17 UTC
And BTW on my workstation, I cannot reproduce this error. It works without problem.

Comment 3 Ian 2021-10-22 09:07:55 UTC
Thanks for correcting and refining the reproducer. I just tried it on fresh F35 beta and still get it, I've included more output below if it helps:

$ sudo dnf install python3-debian

Comment 4 Miroslav Suchý 2021-10-22 20:31:04 UTC
Both errors ("Directory exist" and "Unable to determin") actually comes from ./apt-pkg/init.cc from apt-libs. But from this point I am really lost and I leave it to someone else who knows the apt code or can reproduce it.
