As of this commit from 12 Dec 2023: https://github.com/fail2ban/fail2ban/commit/1024452fe1befeb5a0a014386a81ec183cd45bb5 ....upstream ships its source with the missing async* libraries embedded, which solves the issue for now.
Here is a suggested workaround for Noble until the fix hopefully finds its way into the repos. DISCLAMER: Try at your own risk. I am not an Ubuntu/Debian developer. Next time you receive a proper package update of fail2ban via apt, any of the manually-downloaded files below may cause conflicts and break your system. mkdir -m 0755 /usr/lib/python3/dist-packages/fail2ban/compat wget -O /usr/lib/python3/dist-packages/fail2ban/compat/asynchat.py https://github.com/fail2ban/fail2ban/raw/1024452fe1befeb5a0a014386a81ec183cd45bb5/fail2ban/compat/asynchat.py wget -O /usr/lib/python3/dist-packages/fail2ban/compat/asyncore.py https://github.com/fail2ban/fail2ban/raw/1024452fe1befeb5a0a014386a81ec183cd45bb5/fail2ban/compat/asyncore.py cp -p /usr/lib/python3/dist-packages/fail2ban/server/asyncserver.py{,.original} wget -O /usr/lib/python3/dist-packages/fail2ban/server/asyncserver.py https://github.com/fail2ban/fail2ban/raw/1024452fe1befeb5a0a014386a81ec183cd45bb5/fail2ban/server/asyncserver.py My custom-boostrapped Noble test system is also missing the required 'distutils' Python module by default. The fail2ban package does not have 'python3-setuptools' listed under "Depends" in its control file, which it possibly should at this point. Official Ubuntu images may already have it installed via other packages, but if not, you will need to install it as well: apt install python3-setuptools -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2055114 Title: fail2ban is broken in 24.04 Noble To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fail2ban/+bug/2055114/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
