Fail2ban-1.0.2 don't start anymore on current, please help

I use the Ponce Slackbuild to build version 1.0.2 from fail2ban but i realized it doesn't start anymore since ~ Apr 3

Code:

# /etc/rc.d/rc.fail2ban start

Starting fail2ban

Traceback (most recent call last):

  File "/usr/bin/fail2ban-client", line 34, in <module>

    from fail2ban.client.fail2banclient import exec_command_line, sys

  File "/usr/lib/python3.11/site-packages/fail2ban/client/fail2banclient.py", line 39, in <module>

    from ..server.utils import Utils

  File "/usr/lib/python3.11/site-packages/fail2ban/server/utils.py", line 56, in <module>

    for name, num in signal.__dict__.iteritems() if name.startswith("SIG"))

                    ^^^^^^^^^^^^^^^^^^^^^^^^^

AttributeError: 'dict' object has no attribute 'iteritems'

I tried to replace iteritems() by items() but i have zero knowledge in python and it did not solve the issue.

Does anyone have experienced this error and have a fix ?

EDIT:
by the way there is a small typo in paths-slackware.conf from the Slackbuild:

Code:



apache_error_log = /var/log/httpd/*error.log

apache_access_log = /var/log/httpd/*access.log



should be:



apache_error_log = /var/log/httpd/*error_log

apache_access_log = /var/log/httpd/*access_log

sorry, I'm getting old and my mind is getting clouded, but where do I have updated it (the version on SBo is 0.11.2)?

Spend more time to it and found the fix here

Edited the fail2ban.Slackbuild

I edited the version inside the .slackbuild and luckily it worked fine for some time.

There is a version for 1.0.2 on Slackers.it that have the same error on startup

as it was abandoned on SBo I took maintainership and pushed an update to 1.0.2 switching there too to python3, thanks for the heads-up!

The version on SBo hasn't been updated since 2018 and is meant to be built for python2 so it's not surprising. You should takeover the slackbuild and update it to 1.0.2 on SBo and make sure to change the setup.py line above to python3. (note that on current /usr/bin/python -> python3.11 which adds to the issue you are having)

I understood, but it doesn't matter in this case. The basic rule is that if a fix can be made in the SBo 15.0 repo, it should be made there first, if not then ponce will fix it in his current repo.

The evidence ;)

Hi,

Thank you for taking over the abandoned package, but it looks that it doesn't work in 15.0. After upgrading, running fail2ban-client returns this:

Code:

ERROR: No module named configparser

2024-04-22 15:09:03,771 fail2ban                [12149]: ERROR  Init of command line failed

After installing ConfigParser from slackbuilds, returns this:

Code:

ERROR: type object 'SafeConfigParser' has no attribute '_interpolate_some'

2024-04-22 14:57:58,795 fail2ban                [10749]: ERROR  Init of command line failed

I am not familiar with python and I can't troubleshoot further. Any help?

sorry theodore, I made a little oversight: please change line 75 of the SlackBuild from

Code:

python setup.py install --root=$PKG

Code:

python3 setup.py install --root=$PKG

Fixed.

Yes, that worked, thank you!

Now I have one more reason besides white space to not like python, the v2/v3 problems... :)
