Knowledge Base:Man says no such file or directory for less

From Gentoo Wiki (test)

Synopsis

When asking for a man page, man returns sh: /usr/bin/less: No such file or directory.

user $man emerge
sh: /usr/bin/less: No such file or directory
Error executing formatting or display command.
System command (cd "/usr/share/man" && (echo ".ll 9.9i"; echo ".nr LL 9.9i"; echo ".pl 1100i"; /bin/bzip2 -c -d '/usr/share/man/man1/emerge.1.bz2'; echo ".\\\""; echo ".pl \n(nlu+10") | /usr/bin/gtbl | /usr/bin/nroff -mandoc | /usr/bin/less) exited with status 127.
No manual entry for emerge

Environment

This occurs after a --depclean operation. The sys-apps/less package is not installed (anymore):

user $less
bash: less: command not found

Analysis

When running emerge --depclean, Portage recently wants to remove sys-apps/less as it already found a package that provided the virtual/pager requirement. Unless the user picks the less package themself, it is slated for removal.

Resolution

(Re)Install sys-apps/less:

root #emerge --ask sys-apps/less
