New subject: @Mike, @Alex: Bug in x2gotrinitybindings Debian package (Stable)

6 Feb 2012


      Hi guys,
I am unable to uninstall x2gotrinitybindings.
Its prerm script contains
...
case "$1" in
configure)
rm -f /opt/trinity/bin/kdesktop_lock
mv /opt/trinity/bin/kdesktop_lock.trinity
/opt/trinity/bin/kdesktop_lock
;;
abort-upgrade|abort-remove|abort-deconfigure)
;;

*)
    echo "postinst called with unknown argument \`$1'" >&2
    exit 1
;;
esac
which always breaks with the catch-all condition as uninstalling it
passes "remove":

And I believe postinst contains similar code.
Please fix this. And I think we need some kind of check that in future,
such code doesn't end up in the stable repository (maybe a test box that
does apt-get install --reinstall <packagename> and checks for
errors/warnings in the output before a package goes into stable?).
Kind Regards,
Stefan
