Ubuntu
update-manager package

11.04 Natty Narwhal upgrade fails

Asked by Martin Rehder

tried to upgrade using the "update manager" when it informed me an upgrade was available.

I got this message:
"After your package information was updated the essential package 'ubuntu-minimal' can not be found anymore.
This indicates a serious error, please report this big against the 'update-manager' package and include the files in /varlog/dist-upgrade/ in the bug report

I don't have time to file a bug report and I can't include the files here, although I've saved them should you really want to check them out

Can you give the output of:

cat /etc/lsb-release; apt-cache policy ubuntu-minimal

Thanks

Hmmm, it is a part of the natty repo which is strange. If you run:

sudo apt-get install update-manager-core; sudo do-release-upgrade

What is output (or does it upgrade ok)

# sudo apt-get install update-manager-core

    already installed , nothing to download, etc. etc.

# sudo do-release-upgrade

    it appears to be doing the upgrade, but that's a few hours away. I'll report again when/if it's finished

that appears to have solved the upgrade issue, thanks.

Now, on to make sure everything else works as expected after the upgrade ;)
