Upgrading the server, or upgrading Koha? Your errors suggest Koha.

You didn't say how you installed Koha. Though, I suspect you are trying to 
build from source, which is really hard.
Robin Sheat did point at the Debian instructions, which should work well 
enough on Ubuntu.
But again, that assumes you installed it a particular way, and that you know 
the difference.

If you installed from source, then you can't follow the upgrade instructions 
on:
http://wiki.koha-community.org/wiki/Koha_on_ubuntu_-_packages
Because you never installed it from packages.

You may wish to look at:
http://wiki.koha-community.org/wiki/Moving_an_installation_from_a_regular_install_to_the_Debian_packages
Though, I have not tested these, and make no claims as to whether it is 
current and valid enough.
