我在薄荷17.1 Rebecca Cinammon 64。
当我运行sudo apt-get update时，我收到以下错误。

我浏览了互联网，这似乎是我PPA的一个问题
我更改了＆＃34; Base（Trusty）＆＃34;从默认的官方存储库，一个在英国的存储库，到一个更接近的存储库。
在/etc/apt/sources.list我有：
#deb cdrom:[Linux Mint 17.1 _Rebecca_ - Release amd64 20141126]/ trusty contrib main non-free
我的/etc/apt/sources.list.d/richarvey-nodejs-trusty.list看起来像
deb http://ppa.launchpad.net/richarvey/nodejs/ubuntu trusty main
deb-src http://ppa.launchpad.net/richarvey/nodejs/ubuntu trusty main
