就在最近，我修复了运行 14.04 LTS 的笔记本电脑的无线驱动程序，但现在连接不断断开。所以我四处寻找，发现你可以尝试更新内核，我尝试这样做。当它出现在软件中心时，它说依赖项未得到满足或类似的东西。
然后，我决定使用软件更新程序，看看是否能解决问题。这就是所有问题所在。当我进入软件中心时，它说由于某些问题需要修复。我点击了修复，结果出现了错误。之后，Firefox 根本打不开。尝试下载另一个浏览器也没有用，因为软件中心又出现了另一个问题……我点击了那个红色的小东西，它说运行“sudo apt-get -f install”
当我运行命令时，我得到

mount -o remount,rw /
mount --all
rm /var/cache/apt/archives/*.deb
apt-get update
apt-get remove --purge libunity-core-6.0-9
apt-get install --reinstall unity
apt-get dist-upgrade
apt-get -f install
