Problem:
There is more than enough disk space available and there is no problem with permissions
Resolution:
If the install script encounters a non-zero status code for any command it will issue a message regarding disk space and permissions such as: install error, check disk space/permissions and try again.
The best way to determine whats causing the error is to execute the install script using the command: sh -x install
Using these options will provide debugging information for the script and make it possible to identify the failing command.
Some typical causes for failure are:
a) User written commands of the same name as the UNIX command being picked up before the system command - solution reconfigure the PATH variable so that UNIX system commands are found first
b) Non-existant directories or commands
c) Missing compoents of the operating system
