Dear Maintainer,
I just discovered an article on The Register [1] warning about recent
changes to the license of software downloaded from the Virtualbox
website: The Oracle VirtualBox PUEL does not provide for trial use of
the Oracle VirtualBox Extension Pack software for evaluation purposes
any more[2].
Please check whether virtualbox-guest-additions-iso can still be part
of even non-free with this change.
The minimal change required to this package should be a warning
displayed to the user every time they attempt downloading the extension
pack, IMHO.
