Curtin fails to install Precise in UEFI mode - Unexpected error while running ['mkfs.fat', '-F', '32', '-n', 'efi', '/dev/sda1'] No such file or directory

[Larry Michel]

Trying to deploy Precise on a server in UEFI mode and it fails because curtin is looking for sda1 and there's not a sda1. There is a sda-part1 however.

Curtin bug!

dosfstools on precise does not provide mkfs.fat, only mkfs.vfat.
precise:
$ ls -l /sbin/mkfs.*fat
lrwxrwxrwx 1 root root 7 May 1 2015 /sbin/mkfs.vfat -> mkdosfs

$ dpkg-query --show dosfstools
dosfstools 3.0.12-1ubuntu1.2

$ ls -l /sbin/mkfs.*fat

This was fixed in revision 347.
revision 351 is available in xenial, maas/proposed and maas/next-proposed

I am able to recreate it with version 351 although it seems to be past the partition part. Now it's failing to mount sda1.

This bug is believed to be fixed in curtin in 17.1. If this is still a problem for you, please make a comment and set the state back to New

Thank you.
