How to downgrade all packages automatically?

Asked by Sindhu S

Hi!

I have added a few PPA recently but removed them after upgrading a few packages. Now I want to revert back to those versions available in the archive that is to say I want to downgrade all those packages that are "newer than those available in the archive"

I did a apt-show-versions and here's what I found:

sindhu@sindhu-eee:~/TODO/Code/Projects/Online_Buddies_Tooltip/pidgin-2.6.2$ sudo apt-show-versions | grep "newer"

aptitude --display-format '%p' search 'newer' > ~/output5656.txt

will give you the list of package names, You can then run:

sudo xargs aptitude remove < ~/output.txt

sounds right to me. Watch you dont remove too much or you will screw your system. Downgrading is not very advised.

Tried that, didn't work. The first command: aptitude --display-format '%p' search 'newer' > ~/output5656.txt gives me an empty text file.

try:

aptitude --display-format '%p' search 'fire' > ~/output5656.txt

just to test.

There's gotta be a better way? Anyway, I have resolved my problem doing manual downgrade (ie checking which packages need to be downgraded, searching in synaptic and doing a crtl + e on them and selecting the version)
