[Jochen Voss]

Package: fail2ban
Version: 0.5.4-7

Hi,

when I install and then purge fail2ban, some files are left lying around in
/usr/share/fail2ban:

These files should be deleted when the package is purged.

I hope this helps,
Jochen

Bug#337223: fail2ban: leaves garbage around after purge

[Yaroslav Halchenko]

the key in all this is 
 Stopping fail2ban: Status of fail2ban: fail2ban is not running.
 Not stopping fail2ban
 invoke-rc.d: initscript fail2ban, action stop failed.

So it seems that fail2ban doesn't uninstall cleanly only if it wasn't
running at the moment and stop failed.
That is funny why it matters... 

For now could you please confirm that it uninstalls cleanly if it is
running before you do purge?

Cheeers

Indeed so:

washoe[0] /var/lib/dpkg/info
 less fail2ban.prerm
#!/bin/sh
set -e
# Automatically added by dh_installinit
if [ -x /etc/init.d/fail2ban ]; then
if [ -x `which invoke-rc.d 2/dev/null` ]; then
invoke-rc.d fail2ban stop || exit 0
else
/etc/init.d/fail2ban stop || exit 0
fi
fi
# End automatically added section
# Automatically added by dh_python
dpkg -L fail2ban |
awk '$0~/\.py$/ {print $0c\n $0o}' |
xargs rm -f 2
# End automatically added section

This issue seems to be something to ask about on the mailing list or
debhelper people since I don't want override global ERROR_HANDLER and we
need to have it something else from exit 0 when combining with
dh_python part of postrm.
