Upgrade Mono to 2.4

We recommend using Mono 2.4 on the MindTouch VM; it's compulsory for MindTouch 10.0.0 and higher.  Older VMs may be running a prior version.

To determine the version of mono that you are using run the following command:

mono --version

If you are running Debian Etch, you need to upgrade to Debian Lenny before proceeding.

Note: Make sure you keep the official Debian repository enabled, otherwise the upgrade will fail.

To upgrade to Mono 2.4 (using the backports.org repository) run the following commands:

echo 'deb http://www.backports.org/debian lenny-backports main contrib non-free' >> /etc/apt/sources.list
apt-get update
apt-get install debian-backports-keyring debian-archive-keyring debian-keyring
apt-get update
apt-get -t lenny-backports install mono-common libmono-corlib1.0-cil libmono-corlib2.0-cil libmono-data-tds1.0-cil libmono-data-tds2.0-cil libmono-microsoft-build2.0-cil libmono-security1.0-cil libmono-security2.0-cil libmono-sharpzip0.84-cil libmono-sharpzip2.84-cil libmono-system-data1.0-cil libmono-system-data2.0-cil libmono-system-web1.0-cil libmono-system-web2.0-cil libmono-system1.0-cil libmono-system2.0-cil libmono-winforms2.0-cil libmono0 libmono1.0-cil libmono2.0-cil mono-common mono-jit libmono-i18n2.0-cil mono-gmcs
