Install Mono on Linux

Debian, Ubuntu, and derivatives

Add the Mono Project GPG signing key and the package repository to your system (if you don’t use sudo, be sure to switch to root):

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb http://download.mono-project.com/repo/debian wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list
sudo apt-get update

Run a package upgrade to upgrade existing packages to the latest available. Then install Mono as described in the Usage section.

Note: While the APT package is built against Debian Wheezy, it is compatible with a number of Debian derivatives (including Ubuntu) which means you can use the same repository across all these distributions.

mod_mono (Ubuntu 13.10 and later, Debian 8.0 and later)

To enable mod_mono installation on Ubuntu 13.10 and later, and Debian 8.0 and later (and their derivatives), you will need to add a second repository to your system, in addition to the generic Debian/Ubuntu repository above (if you don’t use sudo, be sure to switch to root):

echo "deb http://download.mono-project.com/repo/debian wheezy-apache24-compat main" | sudo tee -a /etc/apt/sources.list.d/mono-xamarin.list

Alpha update channel

If you want to test bleeding-edge updates to Mono, we now have an alpha update channel. Please report bugs promptly, so we have time to fix them before packages are migrated to stable!

Debian, Ubuntu, and derivatives (alpha channel)

echo "deb http://download.mono-project.com/repo/debian alpha main" | sudo tee /etc/apt/sources.list.d/mono-xamarin-alpha.list
sudo apt-get update

Beta update channel

If you want to test bleeding-edge updates to Mono, we now have a beta update channel. Please report bugs promptly, so we have time to fix them before packages are migrated to stable!

Debian, Ubuntu, and derivatives (beta channel)

echo "deb http://download.mono-project.com/repo/debian beta main" | sudo tee /etc/apt/sources.list.d/mono-xamarin-beta.list
sudo apt-get update
