Everytime I run man it returns an error as if no man page entries were installed. Here's an example:
% man man
No manual entry for man
However, I have installed the packages man-db and man-pages, yet it doesn't return a single entry. I have tried with many commands like man ls, and others.
Also, if i run whatis man, the following is returned:
man: nothing appropriate.
Once you install the packages man-db and man-pages you need to run the mandb command to generate the search database for manpage entries.
EDIT (thanks to @fra-san): If you set the MANPATH environment variable, you also need to unset it. If that variable is set, man ignores the paths specified in the config file man_db.conf.
unset MANPATH so that mandb could use the man_db.conf settings.

unset MANPATH in my .zshrc, then source ~/.zshrc solved it for me too. Thank you!
man --debug manmay output some useful information.man -u manshould try to rebuild the cache.no manual entry for man./usr/share/man. As expected, yourmanconfig lists that one among the directories to search, but then it doesn't add it to the search path, as if it wasn't readable. Oddly,straceshows thatmandoesn't even try to access it. I can't come up with any plausible explanation, unfortunately.
