When I open my update manager i get an error

Jaunty is no longer supported in any way you can think of. It is end of life (EOL). There is no support here and all the Jaunty servers are abandoned

I suggest you upgrade to at least Lucid for continued support. Personally I would ensure your backups are recent and clean install Natty. If you want to upgrade (rather than clean install) then this guide will help:

https://help.ubuntu.com/community/EOLUpgrades

Actually, I've already upgraded to Lucid. That's when this issue came up. Is there something I can do that doesn't require me to slick the laptop and restart from scratch?

Open a terminal: ctrl+alt+t
Verify OS version:
lsb_release -rd

Clean up /etc/apt/sources.list, which means remove all strings incl. 'jaunty'.
Afterwards update package list.
sudo apt-get update

that did the trick! thanks a lot!

After fixing

/etc/apt/sources.list

to get rid of the old jaunty references. I did so the:

sudo apt-get update

But, then I got 404s on fetches for:

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

So, following the brilliant advice, I also needed to to do:

sudo apt-get upgrade --fix-missing

Then it worked like a champ.

I am not sure update-manager will fix this.

I suggest you switch servers using software centre. May help
