Upgrade fails. How should I interpret the apt.log?

Question

when I run

$ sudo do-release-upgrade

I get an error "could not calculate the upgrade"

I see from this link that I am supposed to run this command Could not calculate the upgrade, what happened?

But how should I interpret the apt.log? How do I fix this?

If you can, go through that list of packages and sudo apt-get purge them. Then try:

sudo apt-get update
sudo do-release-upgrade

again.

Also, you can now install Ubuntu 14.04 and you are given the option to upgrade an existing Ubuntu installation that allows you to keep the data in your home folder during the installation process. Always back up your data first of course. You may not be able to keep all the applications you have installed through apt-get and software center but at least you get to keep your downloads, saved data and some of your settings.

Alternatively, you could otherwise choose the option "something else" set your mount point at " / " and make sure to NOT have the option to FORMAT selected . . . again, do not select to format.

Installing without formatting allows you to overwrite the program files and directories while keeping your home folder intact thus preserving personal data and settings. Again, always make a backup.
