The other computer (main one I'm writing from) got the same message after update to 0.131ubuntu1, so I booted with the older kernel (4.15), downgraded initramfs-tools, initramfs-tools-bin and initramfs-tools-core to 0.130ubuntu10 and successfully rebooted with the new kernel. I saved the broken and working initrd.img-4.17.0-5-generic images. Please advise if and where to upload them (27MB each).
