[Logcheck-devel] Bug#515156: logcheck: fails to run after upgrade from etch to lenny

[Evgeni Golov]

Package: logcheck
Version: 1.2.69
Severity: grave
Justification: renders package unusable

Hi,

I've just upgraded a box from Etch to Lenny and my logcheck broke.

I'm getting mails like this from cron:
From: logcheck system account <logcheck at foo.example.com>

Warning: If you are seeing this message, your log files may not have been
checked!

Details:
Failed to get lockfile: /var/lock/logcheck/logcheck.lock

So I started investigating...

/var/lock/logcheck is owned by root:root and is drwxr-xr-x, so the logcheck
user can't write in there.
logcheck.postinst contains this:
        # Set Permissions on install, not upgrade
        if [ ! -n "$2" ]; then
          ...
          # just in case
          chown logcheck /var/lock/logcheck > /dev/null || true
        fi

So we chown the dir to logcheck only on fresh installs, just in case, huh?
/var/lock/logcheck is in the package, thus dpkg is smart and sets it to
root:root again on upgrade. Et voila, we can't lock anymore.

IMHO the permission setting should not be conditional here.

Regards
Evgeni
