Status changed to 'Confirmed' because the bug affects multiple users.

This bug was flagged as a duplicate of 1203534, but now apparently is no longer a duplicate.

As posts in the sometime duplicate suggested the problem occurred in front end of do-release-upgrade command with the NVIDIA driver, and could be avoided by using non proprietary driver, I tried switching from NVIDIA driver to nouveau driver.
As I posted on the erstwhile duplicate bug, the upgrade ran successfully from update-manager GUI.

I think I hit this too.

Very puzzling because I first I used the GUI without invoking it from a terminal. It worked for a while and then silently went away. Not even an oil slick.

When I invoked it from a terminal (sudo update-manager -d) it had this "Signal 0" message (which makes no sense to me since there is no signal 0 -- signals start at 1).

This was enough for me to google and get here. But no solution was presented here, so I went to <https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1203534> (thanks Kelly).

From there I learned that the proprietary nVidia driver was the trigger for the problem. I searched in vain for a GUI tool to switch back to Nouveau (there used to be one in Settings: Hardware, but no more -- pity!). I tried the canned apt-get commands but they didn't work.

What appears to be working is using the command "do-release-upgrade". Thanks to <https://launchpad.net/~ric-almeida> for mentioning this in 1203534

Unfortunately, because do-release-upgrade is working (as I type this), I cannot go back and capture precise information about the "sudo update-manager -d" failure.

When I run sudo update-manager -d:

I tried upgrading to trusty from saucy with the nvidia driver loaded and was unable to recreate this bug. The upgrade continued past extracting the tarball and successfully started running it.

[Brian Murray (brian-murray)]

If anybody has successfully upgraded to Saucy it would be great if they could try the upgrade to Trusty and see if it still fails to start.

On one machine with the nvidia driver the update-manager -d worked. On a second one done this morning this error occurred. Both have the proprietary nvidia drivers.

do-release-upgrade seems to have allowed me to continue.
