Update: not related to proprietary drivers (cannot delete/update my own 2 previous posts), even with those deinstalled, the upgrade will fail.
Have an old VM 19.04 from May: after updating this system & then upgrading to 19.10, it will reliably destroy grub. Let me know if you need support to debug this, I'm reliably able to reproduce it. -- 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."
