There is a tool, ripgrep, with binary name rg.
$ rg
Command 'rg' not found, but can be installed with:
sudo snap install rg # version 0.8.1, or
sudo snap install ripgrep # version 0.10.0
See 'snap info <snapname>' for additional versions.
Obviously I would want the newest version, so:
$ snap install ripgrep --classic # we need --classic, apparently, don't know why
ripgrep 0.10.0 from Chris MacNaughton (icey) installed
$ rg --help
Command 'rg' not found, but can be installed with:
sudo snap install rg # version 0.8.1, or
sudo snap install ripgrep # version 0.10.0
See 'snap info <snapname>' for additional versions.

Command 'ripgrep' not found, did you mean:
command 'zipgrep' from deb unzip
command 'sipgrep' from deb sipgrep
Try: sudo apt install <deb name>

error: cannot find app "ripgrep" in "ripgrep"

So, this is, in my opinion, a fairly terrible experience, so I thought I’d give some feedback about that in the hope that someone can think about it. None of the individual parts here are wrong, but they’re all fitting together in a way that makes the whole experience confusing and unpleasant and less credible, which is a problem.
Command-not-found recommends installing the ripgrep snap to get the rg command, but then doesn’t give me the rg command. (This seems to have been asked about already and then decided not to.) And there are multiple versions of ripgrep in the store, at different versions, and the one with the “canonical” binary name isn’t the most recent version. I was pretty baffled by all this, and I’m more knowledgeable than most users about snaps; I don’t think most people would have known to run it as ripgrep.rg, for example. So the experience here is: I try to run a command, command-not-found tells me to install something to get it, I install that thing, and I still don’t have that command. I don’t know whether this is a bug in command-not-found (don’t recommend things that don’t actually provide the command I typed), the snap ecosystem overall (there are multiple things which all provide the same command), or what. But it’s not a pleasant experience. As I say, nobody is individually doing anything wrong here, but the combined effect of all this is confusing and will likely make people less confident in snaps overall.
