How to downgrade from ubuntugis-unstable to ubuntugis-stable

Question

I have some problems with gdal and I would like to downgrade all of my ubuntugis related libraries on Ubuntu 16.04 again to the stable libraries.

How can I do that?

Answer 1

Install ppa-purge:

sudo apt-get install ppa-purge

Purge the ubuntugis-unstable PPA:

sudo ppa-purge ppa:ubuntugis/ubuntugis-unstable

Add ubuntugis stable repo:

sudo add-apt-repository ppa:ubuntugis/ppa

Install your packages:

sudo apt-get update
sudo apt-get upgrade (or sudo apt-get install gdal etc...)
