Hi there,

I updated yesterday from 1.1.2 to 1.2.0, then i get the same error,
after reading the post, i installed & configure dnsmasq.

then now i got this error :

PXE-T01: File not found
DASH-E3B: TFTP Error - File not found
DASH-M0F: Exiting Option ROM

The DHCP score options 66 & 67 are good (like for the 1.1.2)
i tried to restore old tftpboot directory, same error.
i check the dnsmasq, don’t see any errors.

Fog is installed on a Ubuntu 14.04

ps sorry for my bad english
