[APT::Clean-Installed "0";] doesn't remove packages from experimental repos

I recently moved from Arch Linux to Debian Wheezy. Is there any way to clean the apt cache for the packages that I am not currently using? I tried using this config root@localhost:~# cat /etc/apt/apt.conf APT::Clean-Installed "0"; // auto-remove breaks on meta packages APT::Get::AutomaticRemove "0

Bug#696848: general: USB flash drive unmount problems (both squeeze/wheezy)

Fedora had the same bug and it has been fixed with the recent commits. see if this lengthy report helps. https://bugzilla.redhat.com/show_bug.cgi?id=885133
