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

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

Answer 2

If you are facing problems regarding Broken packages then first of all remove that package by first checking dependencies and then forcefully remove that package, and don't ever forget to reboot when you do make enormous changes in your system. To remove that package use these shell commands

$ sudo su

Then Enter your password

# apt-cache rdepends package-name
# apt-get --purge remove --force package-name

Use these shell commands

# apt-get clean
# apt-get autoclean
# apt-get update
# apt-get upgrade
# apt-get dist-upgrade
# reboot

This worked for me, Try this, I believe this will fix all your problems, Good luck.

Answer 3

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

Replace "PPA_Name" with the name of your PPA.
