我尝试将内核升级到 3.8.2，但没有成功。因此，在了解到 3.8 无法与 bumblebee 配合使用后，我尝试返回并安装 3.5.25。但仍然没有成功。
uname -r说：3.5.0-17-generic
以下是我的问题：
每当我尝试启动更新管理器时，我都会收到以下信息：
E: linux-image-extra-3.5.0-25-generic: subprocess installed
post-removal script returned error exit status 1
我尝试了sudo rm目录，但没有帮助。
$ sudo apt-get purge linux-image-extra-3.5.0-25-generic
