Remove .NET From Linux

This document outlines steps for performing a deep clean on your Linux (Ubuntu 20.04) machine.

An example for performing could be, if your installation does not show in dotnet --list-sdks. Performing this deep clean and reinstalling will solve it in most cases.

Install

wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
rm packages-microsoft-prod.deb


sudo apt-get update
sudo apt-get install -y dotnet-sdk-6.0
dotnet --list-sdks

Remove

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

Deep Remove

sudo apt-get purge --auto-remove packagename

-- OR --

sudo apt list | grep "dotnet"

sudo apt-get remove - purge -y dotnet-runtime-6.0 
sudo apt-get remove - purge -y dotnet-hostfxr-6.0
sudo apt-get remove - purge -y dotnet-runtime-deps-6.0 
sudo apt-get remove - purge -y dotnet-targeting-pack-6.0
sudo apt-get remove --purge -y dotnet-apphost-pack-6.0
sudo apt-get remove --purge -y dotnet-host/now 6.0.0
sudo apt-get remove - purge -y dotnet-apphost-pack-6.0

THE REAL FIX

https://stackoverflow.com/questions/73312785/dotnet-sdk-is-installed-but-not-recognized-linux-ubuntu-popos-22-04 dotnet/core#7699

TL;DR Commands

sudo apt remove 'dotnet*'
sudo apt remove 'aspnetcore*'
sudo rm /etc/apt/sources.list.d/microsoft-prod.list
sudo apt update
sudo apt install dotnet-sdk-6.0

Output Window

Install .NET 6 says "it installed" but something is wrong.
