In /etc/apt/apt.conf.d/50unattended-upgrades I've configured the Allowed-Origins to install all packages automatically. The only exception is that the i386 packages are not being installed automatically because they belong to a different arch (or I at least I suppose that's the reason) thus the unattended-upgrade script skips them. Specifically, those are all the i386 dependencies for the Skype package. Is there any way to tell unattended-upgrade I want all the packages upgraded automatically, regardless of their arch? Perhaps a flag to the Allowed-Origins string?
