package linux-firmware 1.187.3 failed to install/upgrade: installed linux-firmware package post-installation script subprocess returned error exit status 1

[Johannes Kloos]

This happened during an upgrade from Ubuntu LTS 18.04 to 20.04. A `dpkg --configure -a` afterwards worked without trouble - bad interaction of install scripts?

You have yubikey-luks installed, which hooks into update-initramfs and attempts to load a configuration file /etc/ykluks.cfg - which does not exist. As a result, the hook, update-initramfs, and configuring the linux-firmware package (which triggers an update-initramfs) fail.

This is probably a configuration issue. It could also *possibly* be a bug in yubikey-luks (*may* want to just warn if this configuration file is missing), so I'm reassigning to that for now.

Note that yubikey-luks is in universe, so community maintained.
