Error executing help manual pages on Fedora 25 for all kind of man pages

Question

[user1@testMachine ~]$ lsb_release -a

Even lot of help commands are not working, and showing the same error page.

Oh — is this Fedora Atomic, or Fedora Cloud Base? `grep NAME /etc/os-release` — mattdm, Feb 15 '17 at 13:08

You should try to reinstall the man-pages as suggested here http://unix.stackexchange.com/questions/252530/how-to-install-man-pages-on-centos + what @SvennD is saying. — Tolsadus, Feb 16 '17 at 19:30

You should do export MANPAGER=less, check that /usr/bin/man wget works after this and if so look very carefully around your RC files for overrides for MANPAGER and PAGER.

I removed export PAGER configuration from .bashrc and after rebooting its working now, awesome finding. – shahjapan Feb 24 '17 at 09:44

You can try to reinstall the man package :

yum reinstall man

The error you are seeing makes me scared ... 2>/dev/null would send error messages to /dev/null (basically gone) Only very little good reasons to do this.

Have you checked which man and checked if it was a binary ?
