This is image from http://releases.ubuntu.com/focal/ via torrent. I , written it on a usb-stick and loaded PC from it. The bug was after launch installation. Next try of install with same conditions runs the installation normal. I tried re-installations several times (due to another bug of mysql after installation), and this error appears about in 30% tries of install.
I don't know what you talk about /boot/grub/efi.img. I have SSD with BTRFS file system. There is a `boot` partition, remains from previous Ubuntu 19.04 installation. As I said above, on another run of installation it installed normal and work fine with all my partitions. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876477 Title: install broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1876477/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
