首先，我收到此错误，E: Sub-process /usr/bin/dpkg returned an error code (1)因为软件包 ca-certificates 中存在一些问题。然后发现这博客里提到了一些方法，我用的是前三种方法。
之后我发现这问题并尝试使用其答案来解决我的问题但失败了。遗憾的是，第三种方法“ sudo apt-get --purge remove ca-certificates，我猜它会删除所有文件.crt。
当我关注这回答
输出：sudo cp foo.crt /usr/share/ca-certificates/extra/foo.crt是cp: cannot stat 'foo.crt': No such file or directory
无输出：locate foo.crt
