Debian9.12拉伸中的libc6依赖不匹配

Question

在Debian9.12扩展中，我有下面的libc6依赖问题。

sudo apt安装libc6-dev

Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libc6-dev : Depends: libc6 (= 2.24-11+deb9u4) but 2.27-6 is to be installed
             Depends: libc-dev-bin (= 2.24-11+deb9u4) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

我怎么才能修好它？

EDIT1: apt策略libc6

libc6:
  Installed: 2.27-6
  Candidate: 2.27-6
  Version table:
 *** 2.27-6 100
        100 /var/lib/dpkg/status

Answer 1

最后，我在另一个论坛上得到了帮助：https://serverfault.com/a/1004951/302842

这是降低问题包级别的解决方案：

apt install libc6/stretch libc6-dev/stretch libc-dev-bin/stretch libc-bin/stretch locales/stretch sudo/stretch

降级成功了！

Answer 2

您的系统上当前的libc6版本比Debian 9中的版本要新，这使得您无法安装libc6-dev (必须与libc6版本相匹配)。要安装libc6-dev，您必须降低libc6和相关软件包的级别：

sudo apt install libc6/stretch libc-bin/stretch locales/stretch

这可能需要降低其他软件包的评级。

一旦全部完成，您就可以安装libc6-dev了。
