Lucid PPA hosed me! How do I revert?

[wally_bkg]

After "upgrading" using the Lucid PPA (https://launchpad.net/~gstreamer-developers/+archive/ppa) my gstreamer is totally hosed!

The most fundamental stating point for my application no longer works at all:

gst-launch v4l2src ! video/x-raw-yuv, framerate=\(fraction\)30000/1001, width=640, height=480 ! xvimagesink

Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Device '/dev/video0' cannot capture at 640x480
Additional debug info:
gstv4l2object.c(2093): gst_v4l2_object_set_format (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
Call to S_FMT failed for YUYV @ 640x480: Invalid argument
Setting pipeline to NULL ...
Freeing pipeline ...

How do I revert to the stuff in the repos that at least mostly worked?

Fortunately I found an answer on the Ubuntu forums.

Install: ppa-purge package

in a terminal with a long scrollback buffer (so you can manually reinstall what fails to reinstall automatically after the purge)

sudo ppa-purge ppa_gstreamer-developers/ppa

This should be documented on the gstreamer-developers PPA homepave, but if it is I sure couldn't find it!
IMHO the uninstall instructions need to be at least as prominent as the installation instructions.

My advice is to think twice and carefully before installing from a PPA!
