Fetched 143 kB in 3min 43s (637 B/s)

我无法启动 Ubuntu 软件中心。屏幕顶部的栏中出现一个减号。请告诉我我应该按步骤做什么。我有 Ubuntu 14.04 可信赖的 tahr。

对于 GPG 错误，运行sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6AF0E1940624A220 40976EAF437D05B5以导入密钥。

对于 MergeList 问题，运行sudo rm /var/lib/apt/lists/*.

最后，运行sudo apt-get update。
