Setup Ubuntu 20.10 Groovy Gorilla Discussion

Hi! How are you? When I try this:
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add
--->
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
OK

this was a nice introduction to installing rail and ruby and setting postgresql thank you
