As additional confirmation that the installer was trying to write the MBR to the install media, I was successful in installing 20.10 from the same install media on the same hardware by booting the install media to ram, as described here: https://askubuntu.com/questions/829917/can-i-boot-a-live-usb-fully-to- ram-allowing-me-to-remove-the-disk.
I then removed the install media once live, and ran the install, and all installation went without a hitch, and I am now commenting from a fresh, new 20.10 install. In my case, install media is a removable SD card, if that's pertinent. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901137 Title: UEFI on Legacy - grub-install fails due to no space left on ESP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1901137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
