This is happening to me in the Lubuntu 16.04 install. I'm installing from a USB stick. It's a 2008 Macbook with an aftermarket SSD that was wiped - not even a partition table. The "erase disk and install ubuntu" installation method gets all the way past partitioning and copying files, then fails with "unable to install GRUB in /dev/sda" as the dialog title, text is "Executing 'grub-install /dev/sda' failed. This is a fatal error."
When running 'sudo grub-install /dev/sda' from a terminal window, the error is thus: Installing for i386-pc platform. grub-install: error: failed to get canonical path of `/cow'. To add insult to injury, the following dialog is broken; see #1608006. I haven't successfully gotten grub installed yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1588338 Title: Ubiquity fails to install on Mac Mini 2006 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1588338/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
