Install4j Linux installer not working

Question

I made installers for my application, it works on Windows and Mac, but when I try to run the .sh installer file on linux, it fails with this error:

gzip: sfx_archive.tar.gz: not in gzip format

I am sorry, but the installer file seems to be corrupted. If you downloaded that file please try it again. If you transfer that file with ftp please make sure that you are using binary mode.

How can I solve this?

Thanks.

The error message describes the probable reason:

You probably transferred it to the Linux machine in such a way that the line endings were replaced or the installer script was truncated.
