Have you tried with #!/bin/sh instead of using bash?

Anyway, copying a file to MyDocs at install time is not safe, user may have MyDocs unmounted (usb mode etc). A proper way would be a file check in your app and an eventual copy/move.


Have you tried putting the file directly in MyDocs instead of shipping it to /opt and than moving it?

How do you create the package? Madde? Scratchbox? Manual dpkg?
