Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:
E: /usr/share/initramfs-tools/hooks/plymouth failed with return 1.
Sadly there is no error message explaining the exit code 1. Can you edit /usr/share/initramfs-tools/hooks/plymouth and add "set -x" (without the quotes) to the script and then run update-initramfs to get more log output?
