Problem:

When installing Server Express v5.0 on RedHat v5 x86_64 server the following error is displayed:

cp: cannot stat `/media/==>/gzip': No such file or directory

chmod: cannot access `/tmp/gzip': No such file or directory

Failed to gzip this product...your product selection was invalid for this OS.

Resolution:

This error in the install script is caused by a difference in the Linux "tail" command between RedHat v4 and RedHat v5.  The "tail" command in RedHat v5 does not accept an argument beginning with " ", whereas "tail" on RedHat v4 does.  This can be demonstrated easily on the command line, like so:

   tail 2 myfile.txt

This is true even though the "man" page says " " arguments should work on both RedHat v5and RedHat v5.  Thus there is an incompatibility in the "tail" command between the two releases of RH.

If you encounter this error when installing Server Express, it means you are trying to install the wrong product version.  For Red Hat version 5 the level of Server Express must be SX v5.1 or subsequent.  The install script for SX v5.1 has been fixed so it does not depend on "tail 2".
