Removing proposed packages to revert to stable.

[mlind]

You can use APT pinning to accomplish this (http://wiki.debian.org/AptPinning)

Create file /etc/apt/preferences with contents

Package: *
Pin: release a=feisty
Pin-Priority: 1001

Package: *
Pin: release a=feisty-updates
Pin-Priority: 1001

Package: *
Pin: release a=feisty-proposed
Pin-Priority: -10

Priority over 1000 allows downgrading. This should make apt believe that packages from feisty and feisty-updates are newer.


To simulate

sudo aptitude -s upgrade

To perform the downgrade

sudo aptitude upgrade

Thanks mlind, three years and a half later, your post helped me revert maverick from proposed to normal.

Hey, me too!
Thank You for the solution!

The proposed repository completely sucks! It has broken half of my system!
And trying to revert to stable wasted a lot of time!

WTH? Should there be some kind of warning? "If You take the Red pill, there'll be no going back" or something!
This is really frustrated! CANONICAL TAKE A LOOK AT THIS MAJOR PROBLEM!
FIX THIS PLEASE! Or at least create a button that will say: REVERT TO STABLE REPOS
Quit trying to take Gnome Foundation's money and please fix this...

Okay? Because it's really took a go on my nerves...
(and I'm sure not only mine)

Likewise... thanks!

Thanks - this worked in 11.10 too!

Update: I forgot to mention that in 11.10 (and some versions previous) it's 'apt-get' instead of 'aptitude'

The point of the proposed repos is for pre-release testing, which is why they are not selected by default. The Ubuntu documentation does state: "The testing area for updates. This repository is recommended only to those interested in helping to test updates and provide feedback."

OMG!!! You've just help me get rid of the broken system after accidentally activate the proposed repo.
Just 3 words send from 3 years later: I LOVE YOU.
