My Distro
I am using linux mint 22.1 which is based on Ubuntu 24.04.
Straightforeward command
sudo apt-get update
sudo apt-get install -y dotnet-sdk-9.0
But…
I have tried to run this command sudo apt-get install -y dotnet-sdk-9.0 but unfortunately I got no success. I have found that, this command works only with Ubuntu 24.10. For Ubuntu 24.04 I need to use different approach.
Uninstall prior version if exists
sudo apt-get remove dotnet-sdk-8.0
Now, run these commands in a sequence:
sudo apt-get update
sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:dotnet/backports
sudo apt-get install -y dotnet-sdk-9.0
