Unable to upgrade from 14.10 to 15.04

Question

After issuing:

update-manager

And then clicking "Upgrade..." in Software Updater the terminal displays "Checking for a new Ubuntu release" but does not show the dialog to proceed. Which means I am unable to upgrade. PS -UX shows:

trevor    4406  1.8  0.0   4444   800 pts/3    S+   11:45   0:03 /bin/sh -c /usr/bin/pkexec /usr/bin/do-release-upgrade --frontend=DistUpgradeViewGtk3

Any suggestions?

I'm using Ubuntu 14.10 in a VMWARE virtual machine on Windows 7.

You're lucky if you can even update a current install - I haven't been able to run the security updates on mine for a few days now, timeout/connection problem on two internet connections.

Apparently the 15.04 is too popular right now :) If you go to Settings... in the upgrade dialog, and in Software-sources set the server to Main Server or a server near you, it may work better.

I've just updated on another computer and it worked perfectly. I don't think it is a time out issue. – TrevTheDev Apr 28 '15 at 03:58
What server is your software-sources set to? What geographical area are you downloading from? – NoBugs Apr 28 '15 at 04:00

thanks for the solution - it was to switch to the main ubuntu server. If you edit your answer I'll accept. – TrevTheDev Apr 28 '15 at 04:23
@TrevTheDev That is not the solution, I can't even get security updates on my 14.04 - from Main Server, or United States server. It's been this way for days. – NoBugs Apr 29 '15 at 04:24
it work for me!? – TrevTheDev Apr 30 '15 at 02:47
Ok, looks like the problem I was having was due to installing Cyberduck, their repo somehow broke apt-get upgrade (which I didn't know was possible) - https://trac.cyberduck.io/ticket/8788 – NoBugs May 02 '15 at 04:34
