I have a guest with several versions of go installed. It appears that at one point I set alternatives to use 1.20. I now need newer than that by default. I told alternatives to `auto`. I've removed and reinstalled the `go` package, which is 1.22.*. Alternatives still selects 1.18.

Can anyone tell me (1) how I screwed this pooch; and (2) how to recover, other than to manually select 1.22?
