Comment 6 for bug 67209

Thanks for your bugreport and the logs.

How did the ugprade abort? Did it present you a error message? Or just hanged? The logs unfortunately don't indicate what exactly went wrong.

But please try:
$ sudo dpkg --configure -a
$ sudo apt-get install -f
$ sudo apt-get dist-upgrade
$ sudo apt-get install ubuntu-desktop^

That should recover your system.

Thanks,
 Michael
