在 Debian 10 上安装 openssh-server 时出现 libc6 问题

我正在尝试安装 openssh-server。但是，我不断收到此错误：

The following packages have unmet dependencies:
 libc6 : Breaks: openssh-server (< 1:8.1p1-5) but 1:7.9p1-10+deb10u2 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

我尝试复制各种解决方案，但均未成功。一个限制是我不能apt upgrade对所有软件包执行此操作。我必须具体说明可以升级哪些软件包。

以下是我在尝试安装 openssh-server 时执行的命令：

~$ apt search libc6 | grep -i installed

您的来源列表似乎不正确。

打开并查看 </etc/apt/sources.list> 中的版本是否为“Strech”

如果没有，请更新并保存。然后运行#apt-get update 并尝试安装:)
