Can't upgrade from 10.04 LTS to 12.04 LTS

[dep]

Weird thing is, it worked just fine on my notebook. After trying a variety of installers I tried the dist-upgrade c/l option in apt-get and here's what resulted:

dep@dep-desktop:~$ sudo apt-get dist-upgrade
Reading package lists... Done

Calculating upgrade... Done
The following packages have been kept back:
imlib11 libart-2.0-2 libcaldav libcarddav libqt-perl libqt3-mt libwpd8c2a python-sip qca-tls
0 upgraded, 0 newly installed, 0 to remove and 9 not upgraded.
dep@dep-desktop:~$

Anybody know a way around this?

dist-upgrade doesn't upgrade the OS -- it (intelligently) upgrades the installed applications.

If you want to upgrade the OS, then the command line syntax is:

sudo do-release-upgrade

[dep]

alas:

Calculating the changes

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade:
The package 'kubuntu-desktop-kde3' is marked for removal but it is in
the removal blacklist.

This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu

If none of this applies, then please report this bug using the
command 'ubuntu-bug update-manager' in a terminal.

I don't think the package kubuntu-desktop-kde3 is a kubuntu package, Trinity maybe?

You will probably need to uninstall that package in order to proceed or ask them how to fix it. The package is a meta-package so it won't cause other packages to be removed.
