new to pacman. Trying to install VIM, getting a 404 when it tries to download.

Thoughts?  I'm used to apt, not pacman, but this seems like it might be something else.  Is it missing an "apt update" equivalent?  "apt update" is the first thing I usually have to do on a new install, but I guess it's different with pacman?

Any advice?
