When trying to install VirtualBox from Software Boutique on fresh 16.04 get an error "Requires installation of untrusted packages" This requires installing packages from unauthenticated sources.
I can till get it via App Grid etc without any problems, but it stands out especially when everything in Welcome app is for new users.
Looks like the new 2016 key is not present in Software Boutique.
Please try the following. Open up Mate Terminal or press F12 for tilda:
Copy and paste the following 3 lines (one by one) and press enter:
wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -
wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -
sudo apt-get update && sudo apt-get upgrade
Do you still get the errors then?
PS: I checked and App Grid installs Virtualbox 5.0.18 from the Ubuntu repositories, The boutique gets 5.0.20 from Virutalbox and thus needs the keys.
Thanks @wizd3m for the information. Can confirm only the new oracle_vbox_2016.asc key is needed for installing the latest VirtualBox (5.0.20). I’ll commit the correction for Welcome.
Now everything goes fine
