Title:
  package clamav-daemon 0.98.6+dfsg-1ubuntu2 failed to install/upgrade:
  subprocess installed post-installation script returned error exit
  status 2

Status in clamav package in Ubuntu:
  Fix Committed
Status in clamav source package in Vivid:
  Fix Committed
Status in clamav package in Debian:
  Unknown

Bug description:
  [SRU]

  [Impact]

  Bug shows up when user tries to upgrade any previous version of clamav
  to the version which is currently available inside vivid repo. Apt
  crashes with the following error message:

  /var/lib/dpkg/info/clamav-daemon.postinst: 626: /var/lib/dpkg/info/clamav-daemon.postinst: cannot create : Directory nonexistent
  dpkg: error processing package clamav-daemon (--install):
   subprocess installed post-installation script returned error exit status 2

  This happens due to a typo inside postinst script. Variable
  $DEBCONFILE is used incorrectly instead of $DEBCONFFILE (note double
  F) which leads to generation of the incorrect output path.

  This typo is on the path which gets executed only when debconf
  information is available for the package. It means that the issue
  doesn't show up during regular installation but crashes apt during
  updates.

  This issue is important because all clamav users will observe the
  issue while upgrading from Utopic to Vivid.

  [Test Case]

  How to reproduce the issue and make sure that debdiff resolves it:

  [Regression Potential]

  Change is minor and fixes obvious issue. We can't avoid fixing it
  because with this issue in place we won't be able to upgrade clamav in
  the future (all vivid users will meet this issue if we upload an
  updated package without this change).

  [Original Description]

  It looks like the location of the files is wrong in the installer.  Is
  there an updated source perhaps?
