我会尝试sudo apt-get update开始（有时问题很简单！）。考虑包括dpkg --get-selections | grep hold的结果在评论中。

Autoremove也可以提供帮助！

最后，再次尝试使用aptitude（https://unix.stackexchange.com/questions/767/what-is-the-real-difference-between-apt-get-and-aptitude-how-about-wajig）可能会突出问题。

很难在没有更多信息的情况下进行诊断。

SeinopSys在Error installing zlib1g-dev中给出了答案您需要记下所需的软件包版本（在您的情况下为= = 1:1.2.8.dfsg-2ubuntu4），然后运行以下命令将其降级为该版本：

$ sudo apt install zlib1g== 1:1.2.8.dfsg-2ubuntu4

然后您可以尝试重新安装。
