Hello,
I am simply following setup instruction and one of them mention to type in linux:
$ mv red52/ /usr/lib
davy@ubuntu:~/Desktop/openmeetings$ mv red52/ /usr/lib
mv: cannot move red52/' to
/usr/lib/red52': Permission denied
davy@ubuntu:~/Desktop/openmeetings$
--------------------------
Permission denied, what should I do to make it work?
