答案1
您必须彻底清除现有内容并执行全新安装。
使用 GUI 时，其中大部分操作都是自动完成的。但使用命令行时，您必须手动删除剩余的软件包和其他文件。
首先彻底清除/删除您当前安装的不起作用的程序。清理并更新您的存储库缓存和软件包，然后全新安装 gcc。
$ sudo apt purge gcc
$ sudo apt-get autoremove
$ sudo apt update
$ sudo apt upgrade
$ sudo apt full-upgrade
$ sudo apt install gcc
检查命令之间的错误。不应该有错误。如果有错误，请采取建议的补救措施来修复错误。例如，可能会偶尔出现警告或错误，例如：
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
要解决该特定状态，请运行：
$ sudo dpkg --configure -a
然后修复该部分后，继续下一步。
每个命令都应给出一个干净的状态。然后，您将从存储库获得一个全新安装。
