This directory (and version of AlmaLinux) is deprecated.  For normal users,
you should use /8/ and not /8.4/ in your path.

If you know what you are doing, and absolutely want to remain at the 8.4
level, go to https://repo.almalinux.org/vault/8.4/ for packages. 

Please keep in mind that 8.4 no longer gets any updates, nor any security fix's.
