#### **Step 1: Installing the package** <a href="#howtoinstallmonoondebian10-step1-installingthepackage" id="howtoinstallmonoondebian10-step1-installingthepackage"></a>

In the regular Debian repository, Mono is not present. We'll use the official Mono repository to install the Mono packages. It is a simple procedure that won't take more than a few minutes.

* Always be sure to update your system before downloading the latest packages. Run the following command to do it:

```
sudo apt update
```

```
sudo apt install dirmngr gnupg apt-transport-https ca-certificates
```

#### **Step 2: Import GPG Repository Key** <a href="#howtoinstallmonoondebian10-step2-importgpgrepositorykey" id="howtoinstallmonoondebian10-step2-importgpgrepositorykey"></a>
