I'm still running Ubuntu 10.04 with quite a few PPAs. Amongst the PPAs there is Guiodic (Guido Iodice) Lucid quasi-rolling :) PPA which brings most recent versions of many programs to my desktop.

My steps:

  1. sudo update-manager -d
  2. click on upgrade on the appearing window
  3. wait for the magic to happen: prepare to upgrade and setting new software channels

  4. during 'calculating the changes' I will get the following error message in the panel

    An error occurred, please run Package Manager form the right-click menu or apt-get in a terminal to see what is wrong. The error message was: ' Error: Marking the upgrade (E:Error, pkgProblemResolver::Resolver generated breaks, this may be caused by help packages.)'This usually means that your installed packages have unmet dependencies

When I check Synaptic/apt-get I can't find any errors or hint toward broken packages

Could this error be because of many PPA versions being newer than 10.04 original versions?

  • Could you post the error message you get from running `sudo apt-get dist-upgrade`? – Isaiah Feb 23 '11 at 19:50
  • I'm sorry that I did not provide sufficient details in the first place. I hope that now the issue is more clear. – seb Feb 23 '11 at 20:44
  • drop the -d, just try `update-manager` – Jorge Castro Feb 24 '11 at 01:47
  • same error message without the -d – seb Feb 24 '11 at 13:41
  • It seems the direct answer to my question is NO. Should I ask another question regarding the error message? – seb Feb 24 '11 at 19:24
  • @DoR the only error I get is shown in the image above: WARNING: Failed to read mirror file – seb Feb 24 '11 at 19:26
  • @seb I am starting to think that this is a bug/problem with update-manager. – Jorge Castro Feb 27 '11 at 16:02
  • @Jorge found something at [http://list.debian.org](http://lists.debian.org/deity/2002/04/msg00095.html) and [http://debianforum.de](http://debianforum.de/forum/viewtopic.php?f=32&p=766249) and will have a look at the output of `apt-get upgrade -f` – seb Feb 27 '11 at 18:37
  • @seb Excellent! Do keep updating your question with the information, perhaps that output will help solve your problem. – Jorge Castro Feb 27 '11 at 18:41

As hhlp pointed out the update-manager will comment out PPAs before it upgrades you to 10.10.

There are also command line instructions here which talk about do-release-upgrade, which is the supported method of upgrading via CLI:

you have Ubuntu already installed 10.04 and you want to update your version to version 10.10, then click Alt+F2 and run "update-manager", will open a new window.

Click the Update button and start the download and update packages, depending on the state of the network can take a few hours.

this process will comment all your PPA before updated.....
