我是 Ubuntu 新手，可能做了一些愚蠢的事情。
尝试更新，但出现令人厌烦的错误。
Reading package lists... Done
W: Failed to fetch http://archive-canonical.com/dists/&(lsb_release-sc)/InRelease
W: Failed to fetch http://archive-canonical.com/dists/&(lsb_release-sc)/Release.gpg Could not resolve 'archive-canonical.com'
W: Some index files failed to download. They have been ignored, or old ones used instead.
在网上阅读了 abit 之后，似乎这里出了问题：gedit /etc/apt/sources.list
结果如下：

请帮助 ：）
答案1
在您的/etc/apt/sources.list文件中，该行应如下所示：
deb http://archive.canonical.com/ubuntu trusty partner
它不起作用或者部分的格式错误$(lsb_release -sc)。
希望这可以帮助！
答案2
更改源列表文件/etc/apt/
mv sources.list
去https://repogen.simplylinux.ch/generate.php并创建一个新的源列表文件：
nano sources.list
保存并测试。
