[Bug 1571939] Re: Ubuntu GNOME fails to boot after Trusty -> Xenial upgrade

[Erick Brunzell]

Just completed a Trusty w/Wily HWE -> Xenial i386 upgrade with the same
results, so that rules out being arch specific. I've also now
experienced this on three different sets of hardware:

(1) AMD Sempron Processor LE-1250 @ 2.2 GHz
nVidia C61 [GeForce 7025 / nForce 630a] (rev a2)
nVidia MCP61 High Definition Audio (rev a2)
nVidia MCP61 Ethernet (rev a2)
2GB DDR2 RAM

(2) Intel Atom CPU  230 @ 1.60GHz
Intel 82945G/GZ Integrated Graphics Controller (rev 02)
Intel N10/ICH 7 Family High Definition Audio Controller (rev 01)
Realtek RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)
2GB DDR2 RAM

(3) Intel Motherboard: DB43LD
Intel Pentium Dual-Core CPU E5300 @ 2.60GHz
Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)
Intel Corporation 82801JD/DO (ICH10 Family) HD Audio Controller (rev 02)
00:19.0 Ethernet controller: Intel Corporation 82567LM-3 Gigabit Network Connection (rev 02)
3GB DDR2 RAM

What additional info is needed to move this off of incomplete?

Title:
  Ubuntu GNOME fails to boot after Trusty -> Xenial upgrade

Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  Not sure what's gone wrong. After what appeared to be successful
  completion of the release upgrade I'm unable to boot. In recovery mode
  it seems that networking can't be enabled and I get an error about no
  resolv.conf. When trying to boot either the new kernel or the older
  Trusty (Wily HWE) kernel the screen fills rapidly with errors about
  UID 1000 followed by a screen with only a blinking tty1 login, but
  I've never been able to get it to accept my login. I did copy the
  dist-upgrade logs so I'll attach them.
