I have installed fail2ban:
http://forum.xbian.org/thread-4178-post-37899.html#pid37899 (now closed
)
But it can't uninstall now (
as per the output)
Quote:dpkg: error processing package fail2ban (--remove):
installed fail2ban package pre-removal script subprocess returned error exit status 1
Running on BCM2711 with XBian 12.0 - Bullseye, kernel: Linux ARM 32-bit version 6.1.66+
Please what to try?
UPDATE:
I have prefixed three lines of the second "if" confition in /var/lib/dpkg/info/fail2ban.prerm by character "#" and then it removed the package without "pre-removal script" error. Thanks
A bit late, but there are snapshots for such cases. Simply revert to the snapshot that was created before file2ban was installed.
Another alternative would be to comment out the command that produces the error in the maintenance script and try again. I have had to do this several times, Theese scripts are located in /var/lib/dpkg/info/, in your case files /var/lib/dpkg/info/fail2ban*

Yes, It is really helpful, thank you for sharing this tip.
If you already have other security measures in place (such as firewalls, VPNs, or other security software), you may feel that Fail2Ban is no longer necessary.

Thanks for sharing the solution! The idea of using snapshots and editing scripts is beneficial and practical in situations like this.
If the uninstall fails with errors, you might need to manually remove Fail2Ban files

Before commenting out a command, try to understand its purpose. If it's crucial for the package's functionality, you'll need to find a proper solution, not just bypass the error.

Try to figure out what a command is trying to do before commenting it out. You should not simply ignore the error if it is essential to the package's operation; instead, you should investigate possible solutions.

That clears it up. I'll skip installing fail2ban and focus on securing SSH with strong passwords and possibly disabling root login. Also, good point about local-only access; I hadn't considered that. Appreciate the help
