Re: [PLUG] un-upgrade in debian

[LeRoy Cressy <leroy@lrcressy.com>]

it is true that you cannot normally downgrade in Debian but the 
following command will work:

dpkg -i --force-downgrade file.deb
dpkg --set-selections package-name hold

The first line forces a downgrade of a package
the second line places the package status on hold in its present state, 	 
which hopefully prevent apt from upgrading the package.
