Is there a way to install applications using the text based UI that is presented during the OS installation?
During a installation of Ubuntu Server you are presented with a screen which has a list of applications you can check that will be installed. For example, one of those applications is docker. I believe these are called “snaps”.
Is there a way of installing these apps using the same GUI after you have installed the OS?
Solution 1:
You are talking about Subiquity installer. The screenshot of mentioned snap installation menu is below:
The below message is contained in Subiquity's source-code.
These are popular snaps in server environments. Select or deselect with SPACE, press ENTER to see more details of the package, publisher and versions available.
While the list of featured server snaps is contained in the server.section file. I compiled them to table below
