[Bug 1829776] [NEW] apt tries to use whiptail, which won't show

[Daniel Serodio]

Public bug reported:

If I install or update virtualbox-dkms, dpkg needs to ask me to
configure Secure Boot. This works fine using apt-get (or a GUI), but not
apt. When installing via apt, whiptail(1) doesn't show, and the
installation/upgrade process gets stuck, forcing me to kill dpkg then
run "dpkg --configure -a", then reinstall virtualbox-dkms using apt-get.

Example process tree snippet attached.

UEFI Secure Boot requires additional configuration to work with third-party drivers.  The system will assist you in configuring UEFI Secure Boot. To permit the use of third-party drivers, a new Machine-Owner Key (MOK) has been generated. This key now needs to be enrolled in your system's  firmware.  To ensure that this change is being made by you as an authorized user, and not by an attacker, you must choose a password now and then confirm the change after reboot using the same password, in both the "Enroll MOK" and "Change Secure Boot state" menus that will be presented to you when this system reboots.  If you proceed but do not confirm the password upon reboot, Ubuntu will still be able to boot on your system but any hardware that requires third-party drivers to work correctly may not be usable. 17 208
