I upgraded fom Kubuntu 18.04 to 18.10 by running `do-release-upgrade` in the terminal. The process completed without any obvious problems. After rebooting, the system no longer boots, it gets stuck as seen in the attachment.

I managed to fix my system by booting a live system, chrooting into my installation and manually running `update-initramfs -u`. Still, this should be looked into.
