Major package changes
man to man-db package exchange
The package man is substituted by package man-db which provides similar functionality:
man description: The man package includes three tools for finding information and/or documentation about your Linux system: man, apropos, and whatis. The man system formats and displays on-line manual pages about commands or functions on your system. Apropos searches the whatis database (containing short descriptions of system commands) for a string. Whatis searches its own database for a complete word.
man-db description : The man-db package includes five tools for browsing man-pages: man, whatis, apropos, manpath and lexgrog. man preformats and displays manual pages. whatis searches the manual page names. apropos searches the manual page names and descriptions. manpath determines search path for manual pages. lexgrog directly reads header information in manual pages.
