Comment 7 for bug 1749777

Just copying over my description from Bug #1752185 here for reference:

--------------------------------

Bionic:

dpb@bierstadt:~[]$ jq
The program 'jq' can be found:
 + snap 'jq'
 * deb 'jq'

Xenial:

dpb@helo:~[]$ jq
The program 'jq' is currently not installed. You can install it by typing:
sudo apt install jq

--------------------------------

Some Observations that could use cleaning up:

1) why '+' for one and '*' for the other?

2) Neither of these things printed were as nice as what shows up on xenial, missing what the problem was: "program not currently installed", and the what the solution is. Perhaps s/can/cannot/? Still I prefer the previous reading in c-n-f.

3) Users may not be familiar with what 'deb' is, or what 'snap' is for that matter. They are more likely focused on the thing that can help solve their problem (sudo snap install jq, sudo apt install jq).
