我今天刚刚安装了最新版本的 Ubuntu 19.10,我决定做的第一件事就是安装 GNU Screen,使用sudo apt-get install screen
。我的输出是:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package screen
我猜想软件包档案没有完全更新,因为这是一个全新安装,所以我尝试了一下sudo apt-get update
。这是我得到的结果:

我真的不确定为什么它会这样做,除了第一次使用时可能出现一些小问题?计算机肯定连接到互联网,因为我正在那台机器上写这篇文章,我尝试在重新启动后运行命令,但仍然出现错误。我似乎根本无法连接到 au.archive.ubuntu.com。ping au.archive.ubuntu.com
只是坐在那里没有回应。如果有人能帮忙,那就太好了!如果需要任何额外的信息,我很乐意将其编辑到问题中。
答案1
我刚刚在一位评论者的帮助下解决了这个问题。我必须进入“软件和更新”菜单,将“下载自:”菜单更改为主服务器。看来澳大利亚服务器确实出现了暂时性问题,而我的系统没有问题。
对于服务器安装,请参阅如何将 Ubuntu Server 中的镜像从区域镜像更改为主镜像?
答案2
我有同样的问题,
$ sudo apt update
Could not connect to in.archive.ubuntu.com:80 (*2403:8940:ffff::f*), connection timed out Could not connect to in.archive.ubuntu.com:80 (103.97.84.254), connection timed out

Err:9 http://in.archive.ubuntu.com/ubuntu bionic-backports InRelease

编辑/etc/apt/sources.list
对我有用。要编辑,请运行
visudo /etc/apt/sources.list
你只需要将所有替换http://**xx**.archive.ubuntu.com/ubuntu...
为http://archive.ubuntu.com/ubuntu ...
就这样。重试
sudo apt update
答案3
在 ubunto 服务器中将 DNS 更改为 8.8.8.8
echo nameserver 8.8.8.8 | sudo tee /etc/resolv.conf
有用
答案4
我添加了针对同一错误的解决方案,以防其他人遇到与我相同的情况。
就我而言,问题在于配置错误/etc/hosts
。
我对文件中的所有内容进行了注释,然后它又可以正常工作了。
