安装python2.7未满足的依赖关系问题-Ubuntu18.04
安装python2.7未满足的依赖关系问题-Ubuntu18.04
提问于 2019-10-12 21:51:56
我最近清理了重新安装的Ubuntu18.04，现在想要安装python2.7，用于其他各种依赖项，但是我无法这样做。运行sudo apt install python和sudo apt install python-minimal都有非常相似的错误：
python：

硬件信息:产品名称: Acer Aspire A715-72G处理器: Intel(R) Core(TM) i5-8300Hcpu@ 2.30GHz附加图形卡: GP107M GeForce GTX 1050移动电话
我是Ubuntu和Unix的新手，所以我希望这是一个初学者的错误，而且很容易修复。这是我提出的第一个问题，如果我还需要补充的话，请告诉我。
所有的帮助都将不胜感激，非常感谢！
