To be a bit more precise, I found out that this bug isn't limited to VirtualBox, it also happens the same way when I try to install Groovy directly on my hardware (older mainboard without UEFI, no ESP partition, LVM setup, Btrfs filesystem on root).
** Summary changed: - Installation of Ubuntu Groovy in VirtualBox with manual partitioning fails on 'grub-install /dev/sda' + Installation of Ubuntu Groovy with manual partitioning fails on 'grub-install /dev/sda' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893964 Title: Installation of Ubuntu Groovy with manual partitioning fails on 'grub- install /dev/sda' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1893964/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
