Thank you for taking the time to report this bug and helping to make
Ubuntu better. The relevant dpkg terminal log says:

update-initramfs: Generating /boot/initrd.img-5.8.0-34-generic
/usr/share/initramfs-tools/hooks/cryptroot: 18: .: Can't open /lib/cryptsetup/functions
E: /usr/share/initramfs-tools/hooks/cryptroot failed with return 127.

Please run "sudo apt-get install -f" and/or try to re-install
cryptsetup.

** Changed in: initramfs-tools (Ubuntu)
