How To Completely Uninstall Dotnet from Ubuntu 20.10

Ubuntu 7

In this article, we will guide you through the process of completely uninstalling Dotnet from your Ubuntu 20.10 system. This process can be useful if you no longer need the Dotnet framework or if you want to reinstall it for troubleshooting purposes.

Before we dive into the steps, please note that uninstalling Dotnet may affect any applications or projects that are dependent on it. Therefore, it is recommended to back up any important data before proceeding with the uninstallation process.

Quick Answer

To completely uninstall Dotnet from Ubuntu 20.10, you can use either the apt or snap package manager depending on how you installed it. Use the apt remove --purge command to uninstall Dotnet installed via apt, and use the sudo snap remove command to uninstall Dotnet installed via snap. Remember to back up your important data before uninstalling any software.

Uninstalling Dotnet Installed via apt

If you installed Dotnet using the apt package manager, you can uninstall it using the same tool. The apt remove command is used to uninstall software, and the --purge option is used to remove configuration files as well.

Here’s how you can do it:

sudo apt remove --purge dotnet-sdk-5.0.101
sudo apt remove --purge dotnet-runtime-5.0.101

In the above commands, dotnet-sdk-5.0.101 and dotnet-runtime-5.0.101 are the names of the Dotnet packages. If you encounter any issues with the package name, you can try using the major and minor version number only, like this:

sudo apt remove --purge dotnet-sdk-5.0
sudo apt remove --purge dotnet-runtime-5.0

Uninstalling Dotnet Installed via snap

If you installed Dotnet using the snap package manager, you need to follow a slightly different process. Firstly, you need to list the names of the snap packages by navigating to the /snap directory. You can do this using the following commands:

cd /snap
ls

Look for packages starting with dotnet-sdk and dotnet-runtime. Then, remove them using the following commands:

sudo snap remove dotnet-sdk
sudo snap remove dotnet-runtime-60

In the above commands, dotnet-sdk and dotnet-runtime-60 are the names of the Dotnet snap packages. The remove command is used to uninstall snap packages.

Troubleshooting

If you encounter any issues or if the above methods do not work, you can refer to the official Dotnet documentation or seek help from the Dotnet community.
