如何获得 GIMP 2.8？
我尝试使用sudo add-apt-repository ppa:otto-kesselgulasch/gimp并收到此消息：
[sudo] password for neil:
You are about to add the following PPA to your system:
CAUTION!
This PPA could break your installed OS if you use Ubuntu series < Precise. There are dependency issues for Oneiric Ocelot (11.10). Only use it if you know what you do!
There are known issues in Precise Pangolin (12.04).
