Zip file does not open on Ubuntu without Breadth and Additional subjects added.

[sri-rad]

I tried downloading without giving any option for Breadth and Additional, and again with only Breadth. Zip file failed to open both the times. Worked when Additional was added.

Error:

Archive: xxxxx.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of xxxxx.zip or
xxxxx.zip.zip, and cannot find xxxxx.zip.ZIP, period.
