Network available from Live USB but not on upgrade from 14.04.1

Ref: https://www.kubuntuforums.net/showth...upgrade-reboot

I'm running on a 14.10 Live USB to test if networking 'works'; it does.

So there is something about my 14.04.1 that causes a problem when do-release-upgraded. Or, so it would seem. I moved my .kde directory to .kdeOLD and logged out and rebooted. Made no difference. service network-manager still didn't auto-start. So, it isn't anything in my users kde configuration files.

Perplexing.

Added:
/var/log/upstart/network-interface-lo.log provides a "clue" ?

run-parts: failed to exec /etc/network/if-up.d/static-routes: Exec format error
run-parts: /etc/network/if-up.d/static-routes exited with return code 1
Failed to bring up lo.

/var/log/upstart/network-manager.log contains:

(NetworkManager:3743): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Key file does not have group 'connectivity'

/var/log/upstart/networking.log contains:

Use ifdown & ifup to reconfigure desired interface.

Hmm. run-parts: failed to exec /etc/network/if-up.d/static-routes: Exec format error

This from my 14.10 that won't auto-start network-manager:

And from my 14.10 32-bit were network-manager does auto-start:

No static-routes file.

SOLVED!!!! Ah, the great and magnificant Sherlock Tux proves his prowess again! The case was troublesum, but no match for ST.

The culprit was the executable static-routes file. It doesn't exist on my unaffected 32-bit laptop. Removing the executable bit fixed my problem. I'm sure I can simply remove the file, as it doesn't belong here.

I posted my solution on bugs.launchpad.net. See Comment 24 for bug 1354924
