升级到Gnome 16.04.01后，列表文件中的格式错误的条目63
我遇到了14.04版Ubuntu Gnome的一些问题。 几个星期我无法运行更新，每当我尝试时，我都会收到回复“检查您的互联网连接”。 我在这里找到了很多解决这个问题的方案，但它们对我没用。 因此，我今天早上使用可启动USB升级到16.04，我选择升级而不是清理硬盘。 在较新的版本上，我确实尝试更新它，但我现在收到此错误…
sudo apt-get update E: Malformed entry 63 in list file /etc/apt/sources.list (Component) E: The list of sources could not be read. 当我运行以下命令时，我得到了这个输出

你能否建议如何解决这些问题呢？
兴趣点是：
63 deb http://star-www.st-andrews.ac.uk/cran/bin/linux/ubuntu xenial 64 # deb-src http://star-www.st-andrews.ac.uk/cran/bin/linux/ubuntu trusty/
正如错误所说，你错过了一个组件（其他回购的main ， universe等）。 但是，CRAN镜像没有组件，而是使用一个简单的repo ，所以你需要有一个trusty线路的尾随/那里：
deb http://star-www.st-andrews.ac.uk/cran/bin/linux/ubuntu xenial/
更正/etc/apt/sources.list文件中的错误条目。
打开终端并执行以下命令：
sudo nano /etc/apt/sources.list
删除/etc/apt/sources.list文件中的第63行和第64行。
按Ctrl + X关闭文件，用Y确认更改。
现在将存储库重新添加到软件源：
sudo nano /etc/apt/sources.list.d/star-st-andrews.list
将以下行（条目）添加到空文件：
deb http://www-star.st-and.ac.uk/cran/bin/linux/ubuntu/ xenial/ # deb-src http://www-star.st-and.ac.uk/cran/bin/linux/ubuntu/ xenial/
按Ctrl + X关闭文件，用Y确认更改。
参考 ： CRAN存储库
如果在更新软件源时仍然收到错误消息，则应检查/etc/apt/sources.list文件和/etc/apt/sources.list.d夹以查找其他错误条目。 通常，建议在升级系统之前删除外部源。 升级后重新添加源，这将导致正确的输入在正确的位置。
注意 ：在较新的Ubuntu版本中，/ /etc/apt/sources.list文件用于Ubuntu源。
所有外部软件源都作为.list文件驻留在/etc/apt/sources.list.d夹中。
