You might want to look into a Python package manager like <a href="https://pip.pypa.io/en/stable/" rel="noreferrer">pip</a>. 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.

To automatically upgrade all the outdated packages (that were installed using pip), just run the script bellow,

<pre><code>pip install $(pip list --outdated | awk '{ print $1 }') --upgrade
</code></pre>

Here, <code>pip list --outdated</code> will list all the out dated packages and then we pipe it to awk, so it will print only the names.
Then, the <code>$(...)</code> will make it a variable and then, everything is done auto matically. Make sure you have the permissions. (Just put <code>sudo</code> before pip if you're confused)
I would write a script named, <code>pip-upgrade</code>
The code is bellow,

<pre><code>#!/bin/bash
sudo pip install $(pip list --outdated | awk '{ print $1 }') --upgrade
</code></pre>

Then use the following lines of script to prepare it:

<pre><code>sudo chmod +x pip-upgrade
sudo cp pip-upgrade /usr/bin/
</code></pre>

Then, just hit <code>pip-upgrade</code> and voila!

How was the package originally installed? If it was via apt, you could just be able to do <code>apt-get remove python-m2crypto</code>

If you installed it via easy_install, I'm pretty sure the only way is to just trash the files under lib, shared, etc..

My recommendation in the future? Use something like <a href="http://pip.openplans.org/" rel="nofollow">pip</a> to install your packages. Furthermore, you could look up into something called <a href="http://pip.openplans.org/" rel="nofollow">virtualenv</a> so your packages are stored on a per-environment basis, rather than solely on root.

With pip, it's pretty easy:

<pre><code>pip install m2crypto
</code></pre>

But you can also install from git, svn, etc repos with the right address. This is all explained in the <a href="http://pip.openplans.org/" rel="nofollow">pip documentation</a>

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?

How do I update a Python package?
