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:
- sudo update-manager -d
- click on upgrade on the appearing window
- wait for the magic to happen: prepare to upgrade and setting new software channels
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?
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.....
It seems the direct answer to my question is NO. see above comments.
