removing a ppa in ubuntu without using ppa-purge

Question

I had used some third party PPAs to install OpenCV 2.3 on my Ubuntu 11.10. Now while upgrading I faced a few problems with these packages and their unmet dependencies. So I wanted to remove the ppas. But for that I'd be needing a package called ppa-purge which I cannot install now because my package structure seems to be broken.

Any workarounds for this problem?

Thanks.

Answer 1

sudo add-apt-repository --remove ppa:PPA_Name/ppa

Replace "PPA_Name" with the name of your PPA.

Answer 2

Edit /etc/apt/sources.list manually, remove you problem url, then apt-get update, then coninue upgrading.
