: I can't read any manpage yet !
: Man says "xxxxx.1.gz not in compressed format"
: Where does this problem come from ?
Clearly, you have man pages with .gz extension that
are not recognized by gzip. Look at these pages yourself:
maybe they are in clear text.
(In that case, rename them to xxxxx.1.)
If you can't find them, use "man -w xxxxx", which will
tell you the path name, or "man -d xxxxx" which will
spout pages of debugging info, of which you only
want to see the last few lines.
