ubuntu升级时出错（处理时遇到错误）

Question

我正在尝试将 ubuntu 从 11.10 升级到 14.10，但运行时收到此错误消息

sudo apt-get -f install

errors were encountered while processing:
/var/cache/apt/archives/udev-204-5ubuntu20.10_amd64.deb
/var/cache/apt/archives/libgtk2.0-0_2.24.23-0ubuntu1.1-i386.deb
/var/cache/apt/archives/libgtk2.0-0_2.24.23-0ubuntu1.1-amd64.deb
/var/cache/apt/archives/gnome-themes-standard_3.10.0-1ubuntu2_amd64.deb

我该如何解决这个问题？
