无法在 Ubuntu 20.04 WSL 中安装 GCC

Question

我尝试在 WSL 上的 Ubuntu 20.04 中安装 gcc ：

apt -y install gcc 返回错误：

Reading package lists... Done
Building dependency tree
Reading state information... Done
gcc is already the newest version (4:9.3.0-1ubuntu2).
0 upgraded, 0 newly installed, 0 to remove and 194 not upgraded.
1 not fully installed or removed.

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

我尝试使用以下命令修复它：

sudo dpkg --purge --force-depends gcc 
sudo apt-get autoremove -y
sudo apt-get autoclean -y
sudo apt-get clean gcc
sudo apt-get install gcc

但随后出现错误：

    root@LAP123:/home/my_user# sudo apt-get install gcc

如何在 Ubuntu 中安装 gcc？

Answer 1

我可以使用 sudo apt install gcc 安装 GCC，

如果这不起作用，请尝试升级您的软件包。

我在 https://www.systranbox 找到了 YouTube 视频.com/how-to-install-gcc-on-wsl-linux/ 在这方面有些帮助。
