How to install mono 3 on Debian testing?

[haimat]

I want to compile the Unreal Engine on my Debian Liunx (testing) box, which needs the mono package "libmono-corlib4.0-cil" installed that depends on the mono-runtime in version 3. However, on my Debian box I have installed mono in version 4 and "libmono-corlib4.5-cil" (4.5 instead of 4.0). So I tried to install that specific version via

Code: Select all

sudo apt-get install libmono-corlib4.0-cil

However, that gives me:

libmono-corlib4.0-cil : Depends: mono-runtime (< 3.2.9) but 4.2.1.102+dfsg2-8 is to be installed

Can I install mono-runtime in version 3 alongside the currently installed version 4, and if so, how?

Debian testing contains libmono-corlib4.5-cil but not 4.0.
You can check it on https://www.debian.org/distrib/packages
And don't forget make "apt-get update" periodically. And make upgrade also.
