So, while trying to upgrade to 14.04 I encountered this error:
Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade.
Please report this bug against the 'update-manager' package and include the following error message: 'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'
I looked into it and opened the /var/log/dist-upgrade/apt.log log file in a text editor, locating any "broken" packages and remove them with sudo apt-get remove . I had 33 broken packages.
I typed "sudo apt-get update && sudo apt-get upgrade" to see if there were any packages: there were 2 packages which didn't want to update: libboost-filesystem-dev and libboost-thread-dev, so i removed them to see if I was able to get a correct upgrade.
It didn't work.
I'm now getting an error about unresolved dependencies and can't do anything. I tried the following ways to get out of it:
- sudo apt-get -f install, this is the output (it's in italian, sorry about that)
Basing on this, it can't install this "usermetricsservice_1.1.1+13.10.20131003-0ubuntu1_amd64.deb" and even using software center opening it manually, gives error.
- sudo apt-get -u dist-upgrade, similar output as before
This is the output with "sudo dpkg –configure -a" : http://pastebin.com/SEj83RSP
Edit: After rebooting, I managed to fix the broken dependencies through "sudo apt-get -f install", still I can't upgrade ubuntu for the same error as before and I'm not sure sure what's the problem here.
This is the output of "sudo lsof /etc/subuid"
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
Output information may be incomplete.

I had that error just one moment ago, and finally I've resolved. I did this:
1- Try
$ sudo useradd nickname
.2- The response, if you have the error, should be like this: 'useradd: existing lock file /etc/subgid.lock without a PID useradd: cannot lock /etc/subgid, please try again.'
3- Now you have to remove all the files that are making the error, they are, in my case
subgid.lock
. (You can see that in the response says 'existing lock file /etc/subgid.lock', so you have to remove all files that is put in the response). Do this:$ sudo mv subgid.lock /home/youruser/subuid.lock.sav
. Substitutingsubgid.lock
for your error file.4- Try again
$ sudo useradd nickname
. If shows other error file, remove it. If no more error files are there, you should get now the new user.This was very useful for me, so I hope that you can fix the problem =). And sorry for my english because I'm spanish. Good bye and good luck.
