无法下载软件包

Question

需要为我必须做的一些工作下载“traceroute”，我尝试使用“sudo apt-get install”下载软件包。在网上查看后，我看到我可能需要更新软件，但这也不起作用。有任何想法吗？

ubuntu@ubuntu:~$ sudo apt-get install traceroute
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package traceroute is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'traceroute' has no installation candidate

ubuntu@ubuntu:~$ sudo apt-get install update
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package update

PS inetutils-traceroute 不起作用，因此我需要另一个答案才能下载该软件包。

Answer 1

如果提示按 y/n 按 y，请首先运行以下命令以更新存储库：

sudo apt-get update

之后运行此命令更新现有软件，如果提示按 y/n 按 y：

sudo apt-get upgrade

然后使用下面的命令安装traceroute，再次，如果提示按y/n，请按y：

sudo apt-get install inetutils-traceroute
