And how do you install FreeServer 8.3.7 then?
Just press enter when you paste the line.
and i see that there is a file permission problem. you cannot execute the installer.
and that is weird.
what you can try is, in your terminal you can type . passwd root and when asked you chose a password of your choice than enter and re enter is when asked. than logout of your terminal en login again with user root and the password you chosen. then try to execute the freeserver installer again.
