I'm running Ubuntu 9:10 and a package called M2Crypto is installed (version is 0.19.1). I need to download, build and install the latest version of the M2Crypto package (0.20.2).
The 0.19.1 package has files in a number of locations including (/usr/share/pyshared and /usr/lib/pymodules.python2.6).
How can I completely uninstall version 0.19.1 from my system before installing 0.20.2?
You might want to look into a Python package manager like pip. If you don't want to use a Python package manager, you should be able to download M2Crypto and build/compile/install over the old installation.
The best way I've found is to run this command from terminal
sudo pip install [package_name] --upgrade
sudo will ask to enter your root password to confirm the action.
