Installing MonoDevelop on Ubuntu 20.04

To install MonoDevelop on Ubuntu 20.04/20.10, do:

$: sudo apt install apt-transport-https dirmngr
$: sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
$: echo "deb https://download.mono-project.com/repo/ubuntu vs-bionic main" | sudo tee /etc/apt/sources.list.d/mono-official-vs.list
$: sudo apt update
$: sudo apt-get install monodevelop
$: echo "deb https://download.mono-project.com/repo/ubuntu vs-focal main" | sudo tee /etc/apt/sources.list.d/mono-official-vs.list
$: sudo apt update
$: sudo apt upgrade

Note that:

As of this writing (12/22/2020) https://www.monodevelop.com/download/ only shows support for Ubuntu 18.04
I have only tested this on very simple application - console and Gtk2 dialog app
You will notice that I started installing using Bionic (Ubuntu 18.04) and then changed to Focal (Ubuntu 20.04) to upgrade all the libraries
This applies to Pop!_OS 20.10

The following add-ins could not be started MonoDevelop.GnomePlatform

Installing MonoDevelop in OpenSUSE 12.2 from its repository was very easy. When running it for the first time though I got the message: The following add-ins could not be started: The root of the trace shows MonoDevelop.GnomePlatform,2.8 A quick search shows that MonoDevelop depends on libgnomeui . This should have been part of dependencies when installing the application but well.... Below is the screen shot of the error message. References: http://software.1713.n2.nabble.com/MonoDevelop-and-openSUSE-12-1-td7462957.html [2013/04/09] - Same issue observed in OpenSUSE 12.3 and also the same fix. [2014/11/02] - Same issue observed in OpenSUSE 13.3, mondevelop 3.0.6 and the same fix.
