Eclipse 3.8 onwards is required for the latest versions of PyDev (if you need to use an earlier version of Eclipse, stick to PyDev 2.8.x).

Which version of Eclipse are you running? I'm running Ubuntu 12.04 and the Software Center serves me Eclipse 3.7.

To install 2.8.x in Eclipse, do as bohrax mentioned: unselect "Show only the latest versions of available software" and select the 2.8.x.

Answer 2

Not really an answer, but hopefully helpful: I got these errors as well when trying to install PyDev on Ubuntu 12.04. I worked around the problem by unselecting "Show only the latest versions of available software" and selected the 2.6.0 version I know worked on another system.
