I’m cutting off part of the path, since I think it’s probably NDA. No worries, apparently the old location for me hasn’t been updated with new packages, which makes sense.
I decided to check the MS docs and see how a new user would get SSoL running? At the new docs.microsoft site, I found the Install SQL Server on Ubuntu doc.
Following the instructions, I updated the GPG keys and registered the repository with curl:curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add - curl https://packages.microsoft.com/config/ubuntu/16.04/mssql-server.list | sudo tee /etc/apt/sources.list.d/mssql-server.list
My expectation is that upgrading SQL Server on Linux is going to be a lot less painful than upgrading on Windows.
