I am still having probs with centos 4.4. I updated via virtualmin and it appeared to go well...no errors. Then I ran a "recheck config" in vm and got:
The ClamAV program clamscan does not appear to be working properly :

LibClamAV Error: cli_loaddb(): No supported database files found in /var/lib/clamav/daily.inc
ERROR: Not supported data format

/var/lib/clamav/daily.inc is empty.

I then tried #yum install clamav*

Steve,

I'm not an expert on this issue, however my machine was a CentOS 4.4 originally (I leased it over a year ago). Then it updated itself to 4.6 a month or so ago just by me doing a simple "yum update" then rebooting it after that completed. I didn't even realize that this might happen.

Anyway you might check the centOS web site or just give that a try to see if it gets you back up to snuff.

After clamav .92 was successfully updated from .088 by the automated process, clamd would not start. This is Centos 4.6.
I got the same ClamAvLib error with a recheck config as Steve reported. Also, procmail log reported the same error.
Seems that the daily.inc data files have moved from
/var/lib/clamav/daily.inc to /var/clamav/daily.inc.
main.cvd is in both locations.

I manually uncommented and edited /etc/conf.d/virtualman.conf directive
DatabaseDirectory to
DatabaseDirectory /var/clamav # was /var/lib/clamav

and now clamd starts and mail is being scanned by clamav
and recheck config passes.

It remains to be seen if clamav updates go to /var/clamav or elsewhere.

The virtualmin.conf file you refer to is NOT in:

/etc/conf.d/virtualman.conf

In fact the proper location is:

/etc/clamd.d/virtualmin.conf

to make this change in.

Thanks for this thread, as it helped me find, isolate, and fix this problem, as it just bit me in the butt as well.

Right you are. Apologies for my typo.

This is still a problem for me

Redhat Enterprise Linux 4ES

Im still getting the failed dependency

Code:

---> Package clamav-filesystem.x86_64 0:0.92-2.vm.el5 set to be updated ---> Package clamav-update.x86_64 0:0.92-2.vm.el5 set to be updated --> Running transaction check --> Processing Dependency: libclamav.so.1()(64bit) for package: clamd --> Processing Dependency: clamav = 0.88.1-2.vm for package: clamd --> Finished Dependency Resolution .. install failed!

Is there something I should be doing?

Remove the clamd package. It is no longer needed.

rpm -e --nodeps clamd

I'll fix the next revision of the package to handle that obsolete package correctly.
