加不上源http://ppa.launchpad.net/otto-kesselgulasch/gimp/ubuntu/pool/main/g/gimp/。
下载了deb包，用“sodu dpkg -i *.deb “也安装不上，现在想回到2.68都不行了，
显示“Package dependencies cannot be resolved：This error could be caused by required additional software packages which are missing or not installable. Futhermore there could be a conflict between software packages which are not allowed to be installed at the same time.
求解决办法，谢谢！

sudo yum install gimp就什么ok了
