locate can't find files?

[MR ZenWiz]

I'm running Xubuntu 22.04 upgraded from 21.10.  The most recent
updated to locate fails to find a number of files I have in a fairly
well-known location.  Also, the man page for locate talks about
placate and there is no man page for locate AFAICT.

What happened?

FTR, placate also can't find the files.

I did just run the software updater, but I wouldn't think the kernel
would mess this up.

Any clues?

Here's what happens:

(I redacted a couple of files, but they don't contain the pattern.)
