I may be able to help a little.
I did the same last week and had the open office problem.
This in my case was due to a faulty sources list, here is what I did:
edit sources list and make sure they are all set for Breezy.
sudo gedit /etc/apt/sources.list
Here is mine for reference:
Change au to your location.
sudo apt-get update
sudo apt-get dist-upgrade
This worked for me, it downloaded a lot more packages including openoffice and avoids the need to use synaptic.
You may have problems if synaptic isn't working
The login problem cleared up after this too.
Post back and let me know if you have problems
