I too had this problem. Same error message in the grub prompt. I had to burn a live-cd, and boot from it. Reapairing grub from live- system didn't work, it "failed to get canonical path of /cow". So I reinstalled the whole System while keeping all my settings, files, stuff in /home, and so on
that worked quite well and getting things back to normal is done in no time. I know, this is no solution to the bug, but I think it's necessary to give people a hint how to at least access their systems again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848797 Title: After upgrading to 19.10, boot screen shows: "Error: symbol 'grub_file_filters' not found."
