我无法在我的ubuntu中安装gcc
zhangkehu@ubuntu:/$ gcc -v The program 'gcc' is currently not installed. You can install it by typing: sudo apt-get install gcc zhangkehu@ubuntu:/$ sudo apt-get install gcc Reading package lists...

您必须彻底清除所拥有的内容并执行全新安装。
其中大部分是在使用GUI时自动完成的。 但是在使用命令行时，您必须特定于手动删除剩余的包和其他文件。
首先彻底清除/删除您当前安装的内容，但这样做无效。 清理并更新存储库缓存和包，然后重新安装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。 如果是，请解决为解决错误而提供的建议补救措施。 例如，可能偶尔会出现警告或错误，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
然后在修复该部件后，继续执行下一步。
每个命令都应该提供一个干净的状态。 然后，您将从存储库中进行全新安装。
