我有以下错误：
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-kernel-generic : Depends: linux-image-3.11.0-12-generic but it is not going to be installed
Depends: linux-image-extra-3.11.0-12-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
我尝试使用此命令删除它，但没有效果。我遇到了同样的错误。
sudo apt-get purge --auto-remove linux-image-extra-3.11.0-12-generic
sudo apt-get purge linux-image-extra-3.11.0-12-generic
感谢您的所有提示。
编辑：我尝试了 apt-get -f install 但遇到了同样的问题。突触也无法消除这一点。
