.NET applications developed on .NET5.0 can run on some Ubutu versions like (16.04, 18.04, 20.04, 21.04) , if your .NET application has been developed in a lower framework version then probably you need to migrate to .NET5 before install it on Ubuntu.

To install .NET 5 on Ubuntu follow next steps:

1.- Open a shell in Ubuntu and install the Microsoft package repository using the following commands.

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

2.- Install the latest .NET5 SDK.

sudo apt-get update; \
sudo apt-get install -y apt-transport-https && \
sudo apt-get update && \
sudo apt-get install -y dotnet-sdk-5.0

3.- Verify version

dotnet --version
