Package: clamav-daemon
Version: 0.103.3+dfsg-0+deb10u1
Severity: normal
Tags: patch
Dear Maintainer,
in order to limit network bandwith and harddisk capacity, we use a setup
with shared virus patterns. For this, the directory /var/lib/clamav is
shared by multiple systems, only the master system (responsible for
pattern update) having write access.
This breaks the post-install process:
clamav-daemon (0.103.3+dfsg-0+deb10u1) wird eingerichtet ...
/var/lib/dpkg/info/clamav-daemon.postinst: 464: /var/lib/dpkg/info/clamav-daemon.postinst: cannot create /var/lib/clamav/clamav.conf: Permission denied
dpkg: Fehler beim Bearbeiten des Paketes clamav-daemon (--configure):
»installiertes clamav-daemon-Skript des Paketes post-installation«-Unterprozess gab den Fehlerwert 2 zurück
Fehler traten auf beim Bearbeiten von:
clamav-daemon
Which we can fix by modifying /var/lib/dpkg/info/clamav-daemon.postinst
