** Summary changed: - ubiquity targets wrong drive, fails to install grub with nvme disks + ubiquity targets invalid device name with nvme disks, fails to install grub
** Description changed: On Ubuntu 16.04, when installing Ubuntu to an nvme drive, Ubiquity fails to install grub. In ubiquity/misc.py the function default_grub targets /dev/nvme0 instead of /dev/nvme0n1, which is the real name of the device. For single drive scenarios, this can be fixed by filtering out nvme devices from the regex line: old: target = re.sub(r'(/dev/(cciss|ida)/c[0-9]d[0-9]|/dev/[a-z]+).*', - r'\1', target) + r'\1', target) fixed: target = re.sub(r'(/dev/(cciss|ida)/c[0-9]d[0-9]|/dev/(?!nvme)[a-z]+).*', - r'\1', target) - - For multi-drive scenarios, Ubiquity behaves inconsistently between bios - and uefi modes. In UEFI mode, default_grub behaves like the single - drive scenario and only sees the usb media (which it ignores) and the - nvme drive. - - In BIOS mode, there is a device listed at /dev/sda before the nvme - drive. Ubiquity then tries to put grub on /dev/sda regardless that - we're installing to the nvme drive. Grub then fails to install on - /dev/sda. - - This makes Ubuntu a pain to reinstall for our customers if they have an - nvme drive. + r'\1', target) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1600308 Title: ubiquity targets invalid device name with nvme disks, fails to install grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1600308/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
