Ubuntu: Can't upgrade from 15.10 to 16.04



Question:

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

Full contents of logs and sources.list pastebin
/var/log/dist-upgrade/20160501-2239/main.log
/var/log/dist-upgrade/20160501-2239/apt.log
/etc/apt/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?


Solution:1

This is more of a redirect, but when I posted my broken package issue on launchpad (similarly trying to upgrade from 15.10 to 16.04), I got excellent support. In my case my issue was that I had used a foreign source (a ppa) to install some more recent graphics packages, specifically libgl1-mesa-dri, libegl1-mesa, and libgbm1. I had to downgrade those packages to the Ubuntu source versions, and then I was able to proceed with the upgrade. So my suggestion for handling broken package issues is to follow the steps in the OP, e.g.

sudo apt-get update --fix-missing  sudo dpkg --configure -a  sudo apt-get install -f  

and if that fails, consider whether any ppas might be introducing package versions that would interfere with stock Ubuntu packages. Additionally, if you get extremely frustrated (like I did), get support on Launchpad.


Solution:2

I hate to do it, but because I needed a working system I just wiped and reinstalled. Luckily, I have my home folder on a separate partition, so all I needed to do was to format / and reinstall. Thank you to everyone who helped and hopefully this question can serve as valuable troubleshooting material.

Another file that I forgot to check was...

sudo vi /etc/update-manager/release-upgrades

I forgot that I had been changing the value of Prompt=lts to Prompt=normal
