VCH logs bundle only cannot be opened or extracted

[DooDleWilk]

Summary

When downloading the VCH logs from the VCH Management portal (just VCH Logs, not the bundle with Container logs), the produced ZIP archive cannot be opened, as it reports this :

# unzip logs.zip
Archive:  logs.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 logs.zip or
        logs.zip.zip, and cannot find logs.zip.ZIP, period.
