因此,我在大学网络中,这要求我在开始使用互联网之前登录浏览器。我这样做成功,但是在全新安装的Ubuntu上,当我尝试这样做时sudo apt update
,得到以下输出:
$ sudo apt update
Get:1 http://in.archive.ubuntu.com/ubuntu xenial InRelease [2,847 B]
Err:1 http://in.archive.ubuntu.com/ubuntu xenial InRelease

但是当我这样做时wget http://in.archive.ubuntu.com/ubuntu/dists/xenial/InRelease
,我获得了以下输出成功:

显然,我可以通过浏览器打开互联网,wget
但是当我进行sudo apt
(或apt-get
)更新时,会出现此错误。
PS:这个问题与其他线程不一样,因为它们的解决方案似乎不适用于我的线程
wget -SO /dev/null http://in.archive.ubuntu.com/ubuntu/dists/xenial/InRelease
wget -SO /dev/null http://archive.ubuntu.com/ubuntu/dists/xenial/InRelease
我发现,这个问题仅发生在我身上,而不是大学网络中的其他问题。尽管已按照说明设置了网络,但这仍然会发生。任何更多的帮助将不胜感激
编辑:事实证明,大学中我们50%的人都面临这个问题,尽管上个星期之前硬件和sudo apt更新没有问题,但50%的人却没有。感谢@David Foerster一直以来一直为我提供帮助。
就目前而言,问题已经提出给我们学院的网络部门:)
wget -qO- http://in.archive.ubuntu.com/ubuntu/dists/xenial/InRelease | head
什么?
