我该如何修复未满足的依赖关系?
答案1
最后我在另一个论坛上得到了帮助: https://serverfault.com/a/1004951/302842
这是降级有问题的软件包的解决方案:
apt install libc6/stretch libc6-dev/stretch libc-dev-bin/stretch libc-bin/stretch locales/stretch sudo/stretch
降级成功!
答案2
我遇到了类似的问题。我通过这样做解决了它:
开始之前,如果您没有 aptitude,您可以按照以下说明进行安装:能力文档
如果你已经拥有它,你可以继续。首先你需要运行:
sudo aptitude install g++
系统将会询问:接受此解决方案吗?[Y/n/q/?] 您必须选择“n”。
它会建议你降级软件包,并会询问:接受这个解决方案吗?[Y/n/q/?]这次选择“Y”。
它将降级软件包。完成后,你现在可以按如下方式安装 build-essential:
sudo aptitude -f install build-essential
系统将会询问:接受此解决方案吗?[Y/n/q/?] 您必须选择“Y”。
它将安装它。完成后,您可以运行此命令来检查它:
sudo aptitude search build-essential
如果你在结果中看到这一行:
i build-essential - build-essential 包的信息列表
这意味着安装成功,但如果您没有看到它,那么您必须寻找其他解决方案来解决它。
