sudo apt-get update sudo apt-get upgrade sudo apt-get install build-essential sudo apt-get install yum
安装遇见问题：参考解决方案
Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 6601 (aptd) - open (11: Resource temporarily unavailable)
解决方案：sudo rm /var/lib/apt/lists/lock sudo rm /var/cache/apt/archives/lock sudo rm /var/lib/dpkg/lock* sudo dpkg --configure -a sudo apt update
再次执行 sudo apt-get upgrade
一次执行 sudo apt-get install build-essential
测试：重新输入安装：如果已经安装会提示已经安装的版本号：
rpm -qa | grep yum
用yum查看历史安装记录：
yum history
查看yum下载源是否可用：
Yum list
ubuntu历史安装软件查看
apt list --installed
