Bug#641245: /etc/apt/preferences file parse error if all lines are commented out
Package: apt
Version: 0.8.15.6
Severity: normal
Dear Maintainer,
If you have a preferences file where all the lines are commented out apt throws out the following error when trying to do use it.
root@troy-pc:/home/troy# apt-get dist-upgrade
Reading package lists... Done
E: Unable to parse package file /etc/apt/preferences (1)
I think this is pretty bad behavior for apt as sometimes no packages need to be pinned and thus commenting out all the lines for the time being would be desirable.
