package amavisd-new-postfix 1:2.6.4-1ubuntu6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Hi!

Thank you for reporting bugs and trying to make Ubuntu better.

Now, according to the attached logs the failure seems to be because of this:

"Starting amavisd: head: cannot open `/etc/mailname' for reading: No such file or directory
  The value of variable $myhostname is "randallj-desktop", but should have been
  a fully qualified domain name; perhaps uname(3) did not provide such.
  You must explicitly assign a FQDN of this host to variable $myhostname
  in /etc/amavis/conf.d/05-node_id, or fix what uname(3) provides as a host's
  network name!
(failed)."

Have you tried doing what the explanation indicates? If so, has this fixed the problem? If not, could you please follow indicates you and try to start/restart amavisd again.

Please, let us know the results.
