Try with major and minor version only:

sudo apt remove --purge dotnet-sdk-6.0
sudo apt remove --purge dotnet-runtime-6.0

Run these commands:

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

For the situation where dotnet has been installed using snap, you can do the following:

  1. You need to list the names of the snap packages by going to the /snap directory. For example, on Ubuntu 21, my dotnet installations are shown in the following script.

    $ cd /snap
$ ls
...
dotnet-sdk
dotnet-runtime-60
...

  2. Then you can use the following commands to remove the snaps.

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

This was based on the answer for snap packages here: How to list files installed by a snap package?

All you have to do is just put the major version number, for example 3.1 or 5.0. You don't have to put any other minor version number/reference number just major version number will do.

For example for lets say your donet-sdk version is 3.1.416 then just right

sudo apt remove --purge dotnet-sdk-3.1
sudo apt remove --purge dotnet-runtime-3.1

  • FYI https://askubuntu.com/a/1388621/1210606 is the correct answer because this comment from am year ago https://askubuntu.com/questions/1305271/how-to-uninstall-dotnet-from-ubuntu-20-10-completely/1389528#comment2391729_1305274 showed it was a snap. – ChanganAuto Jan 28 '22 at 21:19

    What a mess this is - been stuck for hours trying to install .net 6 & 7 - On my 5th full uninstall and reinstall - The FULL uninstall does not get rid of .NET so attempting a clean install not possible.

    The microsoft instructions dont work - no surprise there, and I cant find any reliable instructions anywhere. None of the above commands remove everything. After using remove or purge, dotnet cmd is still showing. The latest error is Segmentation Fault - corrupted memory.

All you have to do is run this to remove all

sudo apt-get purge dotnet-sdk-*
sudo apt-get purge dotnet-runtime-*

or use version

sudo apt remove --purge dotnet-sdk-6.0
sudo apt remove --purge dotnet-runtime-6.0

You can also use Synaptic to manage all installed versions.

sudo apt install synaptic
