Install MonoDevelop on Debian 10 (Buster). Never had a problem with installing MonoDevelop on Debian before. Even after they removed it from the Debian official repository. That MonoDevelop version was usually very old anyway.

This actually took me some hours to figure out and some support on Debian Facebook group https://www.facebook.com/groups/lifewithdebian/

For Debian 8 and Debian 9 the instructions on MonoDevelops webpage works just fine. Since Debian 10 is just out I figure they haven’t tested (and they also write that) Debian 10 yet. But should be working on newer Debian version. So lets install MonoDevelop on Debian 10.

By default apt doesn’t download from https, so you need to install the following packages first.

sudo apt install apt-transport-https dirmngr

Then we add the key for the repository.

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF

Add the correct repository for Debian 10 (Buster)

echo "deb https://download.mono-project.com/repo/debian buster main" | sudo tee /etc/apt/sources.list.d/mono-official-vs.list

Last thing before installing MonoDevelop, update your package list.

sudo apt update

Then you can install MonoDevelop.

sudo apt-get install monodevelop

Hope you managed to install MonoDevelop to Debian 10. Your Debian 10 system should now have the latest MonoDevelop version installed. Congrats!

If you follow the same path in MonoDevelops instructions for Debian 8 and Debian 9, where they use vs-jessie and vs-stretch. You would assume to use vs-buster. If you use vs-buster and try to install MonoDevelop you will not find it. You will get a message with something like: Unable to locate the package: monodevelop
