[SOLVED] CentOS 7 : Why is man -k and apropos commands not working?

I have just installed CentOS as VM on KVM.
Why is man -k and apropos commands not working?

Quote:

[user1@localhost ~]$ locate apropos
/usr/bin/apropos
/usr/share/man/es/man1/apropos.1.gz
/usr/share/man/it/man1/apropos.1.gz
/usr/share/man/man1/apropos.1.gz

[user1@localhost ~]$ $PATH
bash: /usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/home/user1/.local/bin:/home/user1/bin: No such file or directory

# Not working!
[user1@localhost ~]$ man -k apropos
apropos: nothing appropriate.

# Not working!
[user1@localhost ~]$ apropos man
man: nothing appropriate.

Addendum: man without -k option works, e.g. man man.

Thank you.

Usually this is because the index file hasn't been created. See "man mandb".

Usually the index gets created when man pages are installed, but it may depend on the packages being installed need the mandb utility installed as well. It may also depend on the order they are installed in as well - doing everything in one go usually gets the order correct.
