The installation docs for 22.04 don't mention any dotnet6 package. It's either dotnet-sdk-6.0 for the full SDK or dotnet-runtime-6.0 for the runtime and aspnetcore-runtime-6.0 for ASP.NET Core applications. Did you follow the – Columbarium

Answer 1

This worked for me.

sudo apt remove dotnet*
sudo rm /etc/apt/sources.list.d/microsoft-prod.list
sudo apt update
sudo apt install -y dotnet6

Autotype

Answer 2

If the Dotnet SDK is already installed on the system try the following it will help

sudo apt-get update 

then

sudo apt-get upgrade 

And if prompted yes or no choose yes for the .net framework otherwise if you don't know what you are doing choose no, that command is going to upgrade all your installed software and the kernel, so, be careful if you are relying on some old specific version of packages for your software to run

maybe it will ask you to restart

sudo apt-get upgrade is a 'guns on sparrows' approach for the given problem and does not guarantee to fix it. Please improve or delete your answer because it could lead to unwanted package-upgrades and possible further problems. – Itch
