Fix Nzbdrone Freeze - Install Mono 3.6 Ubuntu •

Nzbdrone is my preferred application for usenet tv PVR automation. Some users have noticed that nzbdrone hangs with the previously recommended mono 3.2 install. Currently the recommended mono version is 3.6 since 3.4 caused database issues and 3.8 is too new to know if it is reliable yet. Therefore we are going to install mono 3.6 on Ubuntu to fix any nzbdrone freezes you may have been experiencing.

There are two methods to upgrade mono to 3.6, compiling from source is the most reliable but takes longer. Using precompiled sources may or may not work for you. If you want a guaranteed working mono 3.6 installation scroll down to the compiling from source guide.

Precompiled Mono 3.6

This will install mono to /opt/
We need to download the mono 3.6 package.
For 32 bit use this package

wget http://download.opensuse.org/repositories/home:/tpokorra:/mono/Debian_7.0/i386/mono-opt_3.6.0_i386.deb
