I see now the issue was with grub-installer. For what it's worth, I might suggest reaching out to the elementary OS team for their resolution to this issue. I've not had any issues on the same hardware installing any version of elementary OS with grub + btrfs, even on versions based on previous versions of Ubuntu where the problem existed and was well documented for Ubuntu.
I don't think the issue is grub or btrfs specifically, but the scripts Ubuntu uses to install grub. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1785491 Title: Ubiquity crash during install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1785491/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
