[Pkg-clamav-devel] Bug#1134489: clamav-freshclam-once.service fails to start

[Timo van Roermund]

Package: clamav-freshclam
Version: 1.4.4+dfsg-1
Severity: normal

Dear Maintainer,

All clamav-freshclam services are enabled by default (see 'preset'):

$ systemctl status clamav-freshclam.service | grep preset
     Loaded: loaded (/usr/lib/systemd/system/clamav-freshclam.service; enabled; preset: enabled)

$ systemctl status clamav-freshclam-once.service | grep preset
     Loaded: loaded (/usr/lib/systemd/system/clamav-freshclam-once.service; enabled; preset: enabled)

$ systemctl status clamav-freshclam-once.timer | grep preset
     Loaded: loaded (/usr/lib/systemd/system/clamav-freshclam-once.timer; enabled; preset: enabled)

My understanding is that:
- clamav-freshclam.service runs clamav-freshclam in the background (as daemon), constantly checking for updates.
- clamav-freshclam-once.service runs clamav-freshclam only when triggered via clamav-freshclam-once.timer.

However, these two services seem to be incompatible: when both are enabled, clamav-freshclam-once.service fails with the following error:

systemd[1]: Starting clamav-freshclam-once.service - Update ClamAV virus database once...
freshclam[2549]: ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).
freshclam[2549]: ERROR: initialize: libfreshclam init failed.
freshclam[2549]: ERROR: Initialization error!
freshclam[2549]: ERROR: Failed to lock the log file /var/log/clamav/freshclam.log: Resource temporarily unavailable
systemd[1]: clamav-freshclam-once.service: Main process exited, code=exited, status=2/INVALIDARGUMENT
systemd[1]: clamav-freshclam-once.service: Failed with result 'exit-code'.
systemd[1]: Failed to start clamav-freshclam-once.service - Update ClamAV virus database once.

What seems to happen is that the log file is locked by the instance of clamav-freshclam that is started by clamav-freshclam.service. And the (second) instance of clamav-freshclam, started afterwards by clamav-freshclam-once.service, fails.

Should one of these services not be disabled by default?
