Offline upgrade from Karmic to Lucid using the alternate CD: The package 'update-manager-kde' is marked for removal but it's in the removal blacklist

[Alessandro Menti]

Binary package hint: update-manager

Upgrading Karmic to Lucid via the "alternate CD" method while offline does not work.
Trying to execute the distribution upgrade by executing "sudo ./cdromupgrade" leads to an error message saying that the "update-manager-kde" package is marked for removal but is in the removal blacklist and the upgrade does not proceed. However, if you download the most recent package lists from the upgrade program first (select "Yes" when asked to download the most recent uploads; after the download has completed you may abort the procedure and disconnect from the Internet, too), the upgrade will proceed, even while being offline.

Ubuntu release: KUbuntu 9.10 Karmic Koala
Package version: 1:0.126.9

I've got same issue with a standard network upgrade. Dialogs flow is very slow and ends with the same error message.

Workaround:
1) Connect the system to the Internet.
2) Start the upgrade with the usual procedure. When prompted to download the most recent updates from the Internet, choose "Yes".
3) Let the installer download the most recent package lists. When the download has finished, you may bring the system offline.
4) The installer will then fail to download the updates - take note of the URLs of the packages you need. Download them using another computer and place the .debs in /var/cache/apt/archives. DO NOT reconnect the original system to the Net - otherwise, it will download a more recent set of package lists and ask you to download further updates.
5) Start the upgrade again, this time choosing NOT to download the most recent updates.

The procedure will complete - make sure you have a rescue CD handy in case the upgrade does not go smooth (in my case, I had to reinstall the boot loader from the KUbuntu "alternate" CD).
