Public bug reported:
It is not possible to resize NVME partitions in the Ubiquity installer.
This appears to affect multiple filesystem types including NTFS and
ext4.
NVME devices have an unusual device format, specifically e.g.
/dev/nvme0n1p1 that has two 'sections' that potentially look like
partitions.
Based on the error message, it seems that this device name is being
parsed incorrectly and it attempts to use the device path /dev/nvme0n1
instead of /dev/nvme0n1p1
You can test this using qemu and a virtual NVME device. If you toggle
the same device/partition between a virtual SCSI/IDE and an NVME device
- the issue appears and disappears.
Commands you can use to replicate the issue - unpack netboot.tar.gz into
the local directory and then
dd if=/dev/zero of=nvme.disk bs=1M count=16384
NVME:
qemu-system-x86_64 -drive file=nvme.disk,if=none,id=drv0,format=raw -device
nvme,drive=drv0,serial=foo -enable-kvm -smp 2 -m 1024 -kernel
xenial/ubuntu-installer/amd64/linux -initrd
xenial/ubuntu-installer/amd64/initrd.gz
SCSI:
qemu-system-x86_64 -drive file=nvme.disk,if=none,id=drv0,format=raw -device
virtio-blk-pci,scsi=off,bus=pci.0,addr=0x7,drive=drv0,id=virtio-disk0,bootindex=1
-enable-kvm -smp 2 -m 1024 -kernel ubuntu-installer/amd64/linux -initrd
