错误：sudo：amazon-linux-extras：找不到命令

Question

系统信息：

Ubuntu 20.04.2 LTS (GNU/Linux 5.4.0-1045-aws x86_64)

问题：尝试运行

sudo amazon-linux-extras install epel -y

和

sudo yum install -y chromium

因为我的Discord机器人需要它，它有以下错误：

Discord 机器人错误：

因此我去查看了故障排除文章在运行 Amazon-Linux 的 AWS EC2 实例上运行 Puppeteer ，因为我们正在运行 Amazon AWS EC2。所以我尝试了命令：

sudo amazon-linux-extras install epel -y

错误是：

sudo: amazon-linux-extras: command not found

sudo yum install -y chromium

错误是：

sudo: yum: command not found

Answer 1

检查软件包安装：确认提供 amazon-linux-extras 的软件包是否安装正确。您可以使用包管理器来检查它是否已安装：

sudo yum 列表已安装 | grep amazon-linux-extras

Answer 2

如果您尝试在计算机上安装 Java --Amazon Linux 2023 AMI 2023，

如果您遇到的错误是

sudo：amazon-linux-extras：找不到命令

这里帮助成功安装Java的命令是

sudo dnf install java-11-amazon-corretto -y
