[Pkg-clamav-devel] Bug#777219: upgrade breaks when User != clamav

[Sebastian Andrzej Siewior]

Package: clamav-freshclam
Version: 0.98.6+dfsg-1
Severity: Important

After upgrade from previous version to the newer where fixed #775400 we
break freshclam from upgrading the database if the owner was != clamav
say Debian-Exim with:

|ERROR: Can't create temporary directory /var/lib/clamav/clamav-431a9586a36e125909ede027609c7aa7.tmp
|Hint: The database directory must be writable for UID 101 or GID 103

it affects s-p-u and unstable. This is the proposed (untested) fix.

I would test it & prepare s-p-u & unstable package later today. But since
nobody noticed this breakage in unstable for a week it might not be that
serious after all or is it?
