How To Install and Build with Monodevelop in Ubuntu 20.04

Ubuntu 5

In this guide, we’ll walk you through the process of installing and building with MonoDevelop in Ubuntu 20.04. MonoDevelop is an open-source integrated development environment (IDE) for programming in C# and other .NET languages. It’s a popular choice among developers due to its cross-platform compatibility and robust set of features.

Quick Answer

To install and build with MonoDevelop in Ubuntu 20.04, you need to add the Mono repository, install the necessary packages, and then use MonoDevelop to build your projects. It’s a straightforward process that allows you to program in C# and other .NET languages on Ubuntu.

Prerequisites

Before we begin, ensure that you have a running Ubuntu 20.04 system and user access to execute sudo commands.

Adding the Mono Repository

First, we need to add the Mono repository to our system. This repository contains the necessary packages for installing MonoDevelop.

sudo apt install gnupg ca-certificates

The sudo command allows us to execute commands with root privileges. apt is the package handling utility in Ubuntu, and install is the command to install new packages. gnupg and ca-certificates are required to securely fetch and install the packages from the Mono repository.

Next, we add the key for the Mono repository:

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

In this command, apt-key adv is used to manage the keys for apt, and --keyserver specifies the server from which to receive the keys. The --recv-keys option is used to fetch the key specified by the following string.

Now, we add the repository:

echo "deb https://download.mono-project.com/repo/ubuntu stable-bionic main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list

Here, echo is used to print the string that follows. The | symbol is a pipe that takes the output of the command on the left and uses it as input for the command on the right. sudo tee is used to write the output to a file with root privileges, and /etc/apt/sources.list.d/mono-official-stable.list is the file where the repository is added.

Finally, we update our package list:

sudo apt update

Installing MonoDevelop

With the repository added, we can now install MonoDevelop:

sudo apt install monodevelop

This command installs the monodevelop package from the repository we added earlier.

Building with MonoDevelop

Once MonoDevelop is installed, you can start it from your applications menu or by running monodevelop in a terminal. To build a project, open it in MonoDevelop and select Build > Build All from the menu. If there are no build errors, your project is ready to run or debug.

Troubleshooting Build Issues

If you encounter any build issues, one solution is to explicitly add the Mono repository to apt to use msbuild instead of the deprecated xbuild. This can be done by following the instructions in the Mono Project documentation.

Another solution is to use the preview-focal main repository instead of the stable repository. This can be done by replacing stable-bionic main with preview-focal main in the repository addition command.

If you encounter a “Debugger operation failed” error, you can try creating a symbolic link to resolve the issue. This involves linking the Mono soft debugger to the Mono hard debugger with the ln -s command.

Conclusion

Installing and building with MonoDevelop in Ubuntu 20.04 is a straightforward process once you understand the steps involved. By adding the correct repository, installing the necessary packages, and troubleshooting any issues that arise, you can have a functional MonoDevelop environment on your Ubuntu system. Happy coding!
