Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:
update-initramfs: deferring update (trigger activated) dpkg-maintscript-helper: error: dpkg: error: unknown option --validate-version [...] dpkg: error processing package initramfs-tools (--configure): subprocess installed post-installation script returned error exit status 1
This should not happen. Which dpkg version do you have installed?
dpkg -l | grep dpkg
