== Install Mono 2.4 packages on Ubuntu Jaunty (9.04) ==

Ubuntu Jaunty (9.04) ships with Mono 2.0.1 packages.  Here are quick instructions for installing the Mono 2.4 packages from Debian sid if you'd rather do that than compile Mono yourself:

* add the following to /etc/apt/apt.conf.d/07default (or create it if it doesn't already exist):

 APT::Default-Release "jaunty";

* add the following to /etc/apt/sources.list :

 deb http://http.us.debian.org/debian/ unstable main

* download the file at http://gist.github.com/162751 (easiest way is to click the 'raw' link and save) and save as, or add to if it already exists:

 /etc/apt/preferences

* install the Debian package signing keys (you'll get a warning the first time running 'apt-get update'; that's what we're fixing with this step):

 apt-get update
 apt-get install debian-archive-keyring
 apt-key add /usr/share/keyrings/debian-archive-keyring.gpg
 apt-get update

* install Mono 2.4 packages:

 apt-get install -t unstable libmono-microsoft8.0-cil \
    libmono-system-runtime2.0-cil libgdiplus libmono-i18n2.0-cil \
    libmono-oracle2.0-cil mono-gmcs

This assumes you don't already have Mono installed.  I didn't check that the package pinning done above in /etc/apt/preferences will work if Mono 2.0.1 packages are already installed.  So it may be easiest to remove Mono 2.0.1 first, then do the above.
