It appears you have a very old version of sed on your target system.
You will likely need to update to a newer version that supports the -i
option in order to get your installation script to work.

What version of sed are you using?  Use --version to report it.

  sed --version

It seems you have run into a problem trying to port software developed
to run on one system over to a different system.  The two systems not
being the same you have run into a classic operating system porting
problem.  This is the way it always used to be in the old days.  POSIX
has helped a lot.  But for example the -i option is not a POSIX
standardized feature.  This is not a bug in sed.  The install script
is simply trying to use a feature that appears in newer GNU sed but
does not exist on your system which has an older GNU sed.

It looks like you are using an ARM system.  Is that right?  (Which is
awesome by the way.)  What is the origination of the operating system?
A software distribution?  Or a self compiled collection?  I can
imagine that whoever provided the system may need to update at least
some of the components of it.  Given your email address I can imagine
the environment and when I worked in a similar environment I often
needed to compile my own updated versions of system software.  You
might want to compile a newer sed for that system.

Alternatively the installation script you are using may need to avoid
using features that are not available on your older software
platform.

If neither are possible then you could modify the script to avoid the
-i option.  I often needed to modify installation scripts in order to
port them to a different system.
