In my case I installed tp_smapi, but on the internet I've found others
that have installed other modules.
When configuring the tp-smapi-dkms package it says it will uninstall the
module first and the it reports: Building initial module for
4.15.0-23-generic
After that it hangs, or so it seems. It turns out that somewhere in
there a script is being called with output redirected to /dev/null. But
under certain circumstances, in my case "the computer is configured for
secure boot", whiptail is being called asking for a password.
Whiptail outputs curses codes to write stuff to the screen but that is
redirected to /dev/null. It then waits for input from the user. I've
debugged this to the point that it is saying this:
- whiptail --backtitle Package configuration --title Configuring Secure
+ whiptail --backtitle Package configuration --title Configuring Secure
Boot --output-fd 12 --nocancel --msgbox Your system has UEFI Secure Boot
enabled. 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. --scrolltext 20
