答案1
您收到该错误是因为 Wily (15.10) 已达到其生命的终结并因此被存档。
如果您确实运行 16.04，则不需要 Wily 存储库，您可以从/etc/apt/sources.list文件中删除它们，或者从/etc/apt/sources.list.d引用 Wuly 的任何文件中删除它们。这将避免您在运行时遇到的错误apt-get update。或者，如果您出于某种原因绝对需要 Wily 存储库，则可以使用old-releases.ubuntu.com代替。archive.ubuntu.com
但是，如果您仍在运行 15.10，则应升级到 16.04。
答案2
您需要删除 Ubuntu Wily PPA。好像不支持。为此，请打开“软件和更新”应用程序，然后转到「其他软件」选项卡并取消选中“乌班图狡猾“ PPA，那么：
sudo apt-get update
