Comment 10 for bug 2003864

I can confirm this happens on a fresh lunar install:

# lxc launch ubuntu-daily:lunar test-freshclam
# lxc exec test-freshclam bash
# apt update && apt dist-upgrade -y
# apt install clamav
# freshclam

Likewise, running again with a cooldown still triggers it:

I couldn't find any reported issues upstream that are related to this, but it seems most likely this is due to the merge from debian from 0.103.6+dfsg-1ubuntu1 to 0.103.7+dfsg-1ubuntu1
