I am running into some trouble with this upgrade, I ran a "do-release-upgrade" and I guess that I wasn't paying attention and the system went from ubuntu 14.04 to 15.10 instead of 14.04 to 16.04. There was a problem with upgrading dconf, but I resolved that by creating a folder that the installer was unable to create for some reason. However, when I try to run the upgrade again for 16.04, it fails with the error "Could not calculate upgrade". Some google searches point to looking at the log "/var/log/dist-upgrade/.../apt.log". I can't determine what is causing the issue because of the magnitude of information in the file.
I used grep and cut to filter the apt.log with the command below and the output is...
"grep Broken /var/log/dist-upgrade/20160501-2239/apt.log |cut -d":" -f1|cut -d" " -f2 > /home/sam/Desktop/broken\ packages.txt"

Another file in that "dist-upgrade" log folder was main.log, but the only line that I found of interest was one "ERROR" line that reads...
2016-05-01 22:44:45,086 ERROR Dist-upgrade failed: 'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'
I don't see how there could be broken or held packages, because of the output of the following...
sam@sam-laptop:/var/log/dist-upgrade$ !349 sudo apt-get autoclean Reading package lists... Done Building dependency tree Reading state information... Done sam@sam-laptop:/var/log/dist-upgrade$ !350 sudo apt-get clean sam@sam-laptop:/var/log/dist-upgrade$ !351 sudo apt-get autoremove Reading package lists... Done Building dependency tree Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. sam@sam-laptop:/var/log/dist-upgrade$ !531 dpkg --get-selections | grep hold sam@sam-laptop:/var/log/dist-upgrade$
More Troubleshooting:
I also tried the following, which completed without error.
sudo apt-get update --fix-missing sudo dpkg --configure -a sudo apt-get install -f
The next thing I thought of was to disable any non-essential repos, so I disabled multiverse and universe repos in sources.list

My last idea is to just boot into single user mode and force remove all the packages that are marked broken, and try the upgrade again. I am tempted to just install over my current install with 16.04 since /home is on a separate partition, but I really don't want to have to re-install all the software on this machine. Also that's the easy way out. Can somebody please help me analyze what is happening?
sudo apt-get upgrade -forsudo apt-get dist-upgrade -forsudo dpkg --configure -a? What doessudo apt-get checkgive? If you get 'Segmentation faulty tree', delete/var/cache/apt/pkgcache.binand/var/cache/apt/srcpkgcache.bin. – emk2203 May 2 '16 at 21:10
