failed to exec /etc/cron.hourly/freshclam: Exec format error

[Josep <josep.spam@…>]

After installing Mailfilter with Antivirus enabled,I keep receiving mails with the following lines:

/etc/cron.hourly/freshclam:
run-parts: failed to exec /etc/cron.hourly/freshclam: Exec format error
run-parts: /etc/cron.hourly/freshclam exited with return code 1

Indeed, that file is an empty executable file:

root@zenbox:~# ls -al /etc/cron.hourly/freshclam
-rwxr-xr-x 1 root root 0 2010-12-03 08:11 /etc/cron.hourly/freshclam

[jacalvo@…]

That file is no longer used in recent versions, the correct file now is:

/etc/cron.d/clamav-freshclam

You can upgrade to the latest packages in case you haven't done yet and remove the old /etc/cron.hourly/freshclam without problem.

Replying to jacalvo@…:

That file is no longer used in recent versions, the correct file now is:

/etc/cron.d/clamav-freshclam

You can upgrade to the latest packages in case you haven't done yet and remove the old /etc/cron.hourly/freshclam without problem.

Relevant lines in my /etc/apt/sources.list:

deb http://ppa.launchpad.net/zentyal/2.0/ubuntu lucid main
deb http://archive.canonical.com/ubuntu lucid partner

I have done "aptitude update; aptitude purge ebox-antivirus". This still leaves related files in /etc/cron.hourly. I have removed by hand all files related to this package.

I have reinstalled ebox-antivirus

I assume this must be the latest package available, right? Now, checking folder /etc/cron.hourly ...

root@zenbox:~# ls -al /etc/cron.hourly/freshclam
-rwxr-xr-x 1 root root 0 2010-12-08 18:44 /etc/cron.hourly/freshclam

While in folder /etc/cron.d ...

root@zenbox:~# ls -al /etc/cron.d
total 40
drwxr-xr-x   2 root root  4096 2010-12-08 18:43 .

So, unless you have just made the changes to the package and it is not yet available to the public, the solution you refer is not right. I still have an invalid executable in /etc/cron.hourly, and the file /etc/cron.d/clamav-freshclam does not really exist.

[jacalvo@…]

Sorry, you are right, the old /etc/cron.hourly/freshclam that is no longer used, is still created (empty) in the postinst of the package. I'll remove that asap.

But if you really have ebox-antivirus 2.0.4 (double check it with apt-cache policy), I don't understand how your /etc/cron.d/clamav-freshclam file doesn't exist... is the Antivirus module enabled?

[Josep <josep.spam@…>]

You'r right. File /etc/cron.d/clamav-freshclam is created when the Antivirus module is actually enabled.
