ubuntu安装yum

最近搞了一台服务器，自己折腾的时候用到了yum，发现使用apt-get下载yum时一直报错：

root@iZbp1cml7iso80jlaxx2uZ:/tjy# apt-get install yum
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package yum

网上搜了半天，解决方案无非是：

1 2	apt-get update apt-get upgrade

但是根据我的实际情况，更新apt的库后没有用

最终解决方案：

备份sources.list文件

1	sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

修改源

1	sudo vim /etc/apt/sources.list

进入vim后

进入Normal模式（按Esc键）。
输入ggdG并按Enter键。这将会从当前光标位置开始到文件的最后行都被删除。
删除过后，我们先查看服务器的ubuntu版本

进入清华镜像源获取镜像内容，

选好ubuntu版本后复制框中内容至/etc/apt/sources.list

在/etc/apt/sources.list的第一行再加入：

deb http://archive.ubuntu.com/ubuntu/ trusty main universe restricted multiverse
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19

- 在我的机子上，sources.list内容如下：

  ```sh
  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
  deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse
  # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse
  deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse
  # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse
  deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse
  # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse
  
  deb http://security.ubuntu.com/ubuntu/ jammy-security main restricted universe multiverse
  # deb-src http://security.ubuntu.com/ubuntu/ jammy-security main restricted universe multiverse
  
  # 预发布软件源，不建议启用
  # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse
  # # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse

最后输入”:wq”再回车就修改完毕了

修改过后，需要从新的源加载

1	sudo apt-get update

之后我们再安装yum：

1	sudo apt-get install yum

这时候我遇到了报错：

root@iZbp1cmlu7iso80jlaxx2uZ:/etc/apt# sudo apt-get install yum

从报错提示可看出没有指定的公钥，执行命令安装指定的公钥即可

安装公钥(后8位即可代表公钥)：

1 2	sudo apt-key adv --recv-keys --keyserver keyserver.Ubuntu.com 437D05B5 sudo apt-key adv --recv-keys --keyserver keyserver.Ubuntu.com C0B21F32

安装公钥后，重新加载apt库

1 2	apt-get update apt-get upgrade

出现了以下警告：

The following packages have unmet dependencies:
 python3-six : Breaks: libpython-stdlib (< 2.7.18) but 2.7.5-5ubuntu3 is to be installed
               Breaks: python-minimal (< 2.7.18) but 2.7.5-5ubuntu3 is to be installed
 python3-yaml : Breaks: libpython-stdlib (< 2.7.18) but 2.7.5-5ubuntu3 is to be installed
                Breaks: python-minimal (< 2.7.18) but 2.7.5-5ubuntu3 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

我们根据提示安装所需即可

1 2	sudo apt install libpython-stdlib sudo apt install python-minimal

最后，终于安装成功！

1	sudo apt-get install yum

成果展示：

后续问题：

安装好yum后，尝试使用yum安装一些应用，结果报错：

root@iZbp1cmlu7iso80jlaxx2uZ:/tjy# yum -y install mlocate
There are no enabled repos.
 Run "yum repolist all" to see the repos you have.
 You can enable repos with yum-config-manager --enable <repo>
root@iZbp1cmlu7iso80jlaxx2uZ:/tjy# yum repolist all
repolist: 0

这是因为我们没有repo文件….

其实Linux系统基本上分为两大类:

RedHat系列：Redhat、Centos、Fedora等
