I searched web, first several links in SERP are not the offical one from microsoft. I tried them and failed to install mssql due to errors Error: 'deb [arch=amd64 https://download.docker.com/linux/ubuntu \ xenial \ stable' invalid] or Can’t install MS SQL Server on Ubuntu 21.10. At last I follow the instruction from microsoft. I successfully installed mssql server in my wsl+ubuntu22.04 environment. curl -fsSL https://packages.microsoft.com/keys/microsoft.asc | sudo gpg --dearmor -o /usr/share/keyrings/microsoft-prod.
