安装yum:
sudo apt-get install yum
执行报错 E: Package 'yum' has no installation candidate
解决:更换镜像源,找到自己的系统版本(如本系统为Ubuntu24.04)用vim进行更换,网址:
ubuntu | 镜像站使用帮助 | 清华大学开源软件镜像站 | Tsinghua Open Source Mirrorhttps://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
修改镜像源:
sudo vim /etc/apt/sources.list
第一行:deb http://archive.ubuntu.com/ubuntu/ trusty main universe restricted multiverse
deb http://archive.ubuntu.com/ubuntu/ trusty main universe restricted multiverse
# 默认注释了源码镜像以提高 apt update 速度,如有需要可自行取消注释

更新软件源和软件包:
sudo apt update
sudo apt-get upgrade
sudo apt update:从软件源(repositories)中检索最新的软件包列表信息,并不会更新已安装软件,只是确保apt下载的软件是最新的。
sudo apt-get upgrade:升级系统上所有可升级的软件包到最新版本。这个命令会检查所有已安装的软件包是否有可用的更新,并自动下载和安装这些更新。
注意:两个都要执行。
