This could be due to a “bad” mirror. To see if this is the case, make the following change and try again:

mirrorlist=https://mirrors.almalinux.org/mirrorlist/$releasever/baseos
# baseurl=https://repo.almalinux.org/almalinux/$releasever/BaseOS/$basearch/os/

to

# mirrorlist=https://mirrors.almalinux.org/mirrorlist/$releasever/baseos
baseurl=https://repo.almalinux.org/almalinux/$releasever/BaseOS/$basearch/os/
