Yes, the "Error-Log" comes only when freshclam will be started from reboot
via cron job
Did I understand you well?
@reboot host -t txt current.cvd.clamav.net /etc/clamav/clamav_opts sigs_update 0
Hmm. I have never used cron events such as @reboot
and I don't have a file /etc/clamav/clamav_opts
I was expecting a script /etc/cron.daily/freshclam but I must
have written mine myself (though anacron would use such a file).
Are you using Ubuntu clamav .deb packages or ones from ClamAV ?
Reading about @system cron events, I would not use it to
update the clamav database. Instead I would rely on anacron
noticing that we missed running freshclam at the proper time,
so start it now if appropriate.
That or stick with the clamv-freshclam daemon/service.

Hi @ all,
i have this problem with freshclam since long time and I can't fix it
(Ubuntu
22.04.1)
When i run freshclam with a cron job (@rebot) this log come's up:
This is at reboot ?
I think the problem is that the cron job is starting freshclam
before your network - specifically your DNS - is ready.
When you run the command on a system that has been up for some time
the DNS is ready so the problem does not occur.
Two *possible* solutions:
1. Change your cron job to include the line
host -t txt current.cvd.clamav.net
before it runs "freshclam".
This may trigger the system to start the DNS service so that it is
ready when freshclam wants it.
2. Switch to using the systemd service "clamav-freshclam".
First disable your freshclam cron job, perhaps by
moving /etc/cron.d/clamav-freshclam elsewhere (if it exists).
Then something like
sudo systemctl enable clamav-freshclam
sudo systemctl status clamav-freshclam.service
----
If I am right this isn't really an issue with freshclam
but with the way that all the pieces of the system have been put together.
I note that the Ubuntu 22.10 clamav packages are designed to work with
systemd in preference to cron and I don't remember it having changed
since at least Ubuntu 20.04.

When I run the same command later in the day, all is fine.
What can I do to solve the issue?
