E: 无法纠正问题，您持有损坏的软件包 - libpq-dev

我正在尝试安装 libpq-dev，但在尝试执行此操作时收到错误。

当我跑步时：

sudo apt-get install libpq-dev

我收到以下错误：

Reading package lists... Done

             Depends: krb5-multidev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

当我跑步时apt-cache policy libpq5：

我该如何解决这个问题？

答案1

看起来libpq-dev软件包需要libpq5 9.5.5-0版本，而您有9.6.0-1版本。您必须强制降级libpq5软件包：

sudo apt-get install libpq5=9.5.5-0ubuntu0.16.04

接下来是krb5-multidev安装：

sudo apt-get install krb5-multidev

更新

我不知道为什么会发生这种情况，但是如果你从终端下载这两个版本，libkrb5-3默认libgssapi-krb5-2情况下它会安装该1.13.2+dfsg-5版本。应用以前的方法来解决此问题：

sudo apt-get install libgssapi-krb5-2=1.13.2+dfsg-5
sudo apt-get install libkrb5-3=1.13.2+dfsg-5
