Ubuntu GNOME Saucy -> Trusty upgrade ends in a black screen

[Erick Brunzell]

Just testing Ubuntu GNOME upgrades via "update-manager -d -c" and all seemed to go fairly well but when I'd expect to be asked to remove packages I got a black screen with a blinking cursor. I finally did a hard reset and all seems well but I see this at the end of the main.log:

I suspect the entire log is attached.

It does appear that all of the desired logs are attached, but I also need to rinse and repeat to be sure this wasn't just a fluke.

I have not been able to reproduce this but I'll leave it open for a while and see what happens.

This may have had something to do with it:

2014-01-21 01:06:20,610 DEBUG need_server_mode(): can not find a desktop meta package or key deps, running in server mode
2014-01-21 01:06:33,120 DEBUG Running KeepInstalledSection rules

@ Brian,

That install had been heavily modified, most specifically adding 'gnome-session-flashback' and switching to 'lightdm' from 'gdm'. And the upgrade actually turned out OK other than having to perform a hard reset and running "apt-get -f install" to see what needed to be removed.

I'm almost tempted to call this invalid, but at the very least it should be a low priority .......... or maybe marked to expire if no one confirms????
