[1/1] UBUNTU: [Config] fix up postinst to ensure we know which error is which

We are seeing cases of errors from the postinst saying "Failed to
symbolic-link", but there are more than one of these in the script.
Convert all of these errors to errors without newline which will trigger
perl to add "at FILE line line NN.".  Also be consistant about format
and spaceing for error string ($!) printing.
