在debian 10 buster上安装snmp mibs downloader

我已经在带有debian 10 buster的linux机器上安装了net snmp，现在我需要安装snmp MIB downloader

虽然我以前跑过

sudo apt-get update

执行时：

sudo apt-get install snmp-mibs-downloader

显示以下屏幕输出，表示找不到请求的数据包：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package snmp-mibs-downloader 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 'snmp-mibs-downloader' has no installation candidate

我在互联网上看到，这可以通过编辑文件来解决

/etc/apt/sources.list.d/nonfree.list

但它并没有解释应该写些什么

非常感谢允许我安装snmp mibs downloader的任何帮助。

您/etc/apt/sources.list应该如下所示：

deb http://deb.debian.org/debian/ buster main contrib non-free
deb http://deb.debian.org/debian/ buster-updates main contrib non-free
deb http://security.debian.org/debian-security buster/updates main contrib non-free

那你能得到最新消息吗
