不同版本的Ubuntu使用清华镜像，加速Ubuntu软件下载速度

本博客目的： WSL的Ubuntu软件仓库更换清华镜像源。
提示： 这个是更新Ubuntu的软件仓库，而不是pip、conda更换清华镜像，记得自己的目的，别看错了。

使用WSL跑深度学习挺不错的，但是用wsl安装linux软件可能会存在部分问题，由于WSL里面的Ubuntu软件仓库是默认的源，有时候可能会造成网络连接问题，或者下载速度很慢，更换为清华镜像或者阿里云镜像会带来Ubuntu软件的快速下载，优化软件使用体验。

阿里云Ubuntu软件仓库：https://developer.aliyun.com/mirror/ubuntu

该镜像仅包含32/64位x86架构处理器的软件包，在在 ARM(arm64, armhf)、PowerPC(ppc64el)、RISC-V(riscv64) 和 S390x 等架构的设备上（对应官方源为 ports.ubuntu.com）请使用 ubuntu-ports 镜像。

现在的win都是64位的，对应的WSL几乎都是64位的，因此对大多人都是适应的。

1. 备份源软件配置文件

Ubuntu的系统自带的配置文件在/etc/apt/source.list中，因此我们需要首先备份该配置文件，否则删了的话，如果镜像镜像也不可用，就很难受了。

首先进入配置文件目录，如下命令：

cd /etc/apt

备份的命令如下，sudo表示启用管理员权限，cp表示复制，就是把后面的sources.list文件复制一份，复制的文件以source.list.bak命名。

sudo cp sources.list sources.list.bak

2. 复制镜像源

因为不同的Ubuntu版本对应的镜像是不同的，所以需要复制的命令也不一致，大家可以根据自己的Ubuntu版本来复制命令。他们的命令是很相似的，区别就是括号里面不一样。点击下面挑战链接，复制对应的镜像源配置。镜像速度的话，这个看地区差异，不太好说。

3. 修改软件源配置文件

使用如下命令打开配置文件：

sudo vim source.list

打开该文件之后，使用命令ggdG将该文件内容删除，然后按a键编辑，把复制过来的清华镜像直接右键就可粘贴。

如下所示。

保存的话，需要切换到英文输入，先Esc，然后冒号:，再按wq保存退出即可。

4. 更新软件包列表，升级软件包等内容

更新软件包列表代码如下，可以看到Get的地址是阿里云的镜像。

sudo apt-get update

升级软件包如下命令：

sudo apt-get upgrade

5. 从仓库中下载其它软件

直接使用命令sudo apt-get install xxx就可以安装对应的xxx软件，

如下所示：

sudo apt-get install gedit

可能存在的问题

现在的清华镜像Ubuntu软件仓库，我使用学校教育网无法连接，不知道是因为我的ip问题，还是清华镜像仓库暂时不可用的问题。

个人觉得是因为我的ip段被清华的Ubuntu软件仓库拉黑了。。。

连接问题如下：

2 packages can be upgraded. Run 'apt list --upgradable' to see them.
W: Failed to fetch https://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/focal/InRelease  Cannot initiate the connection to mirrors.tuna.tsinghua.edu.cn:443 (2402:f000:1:400::2). - connect (101: Network is unreachable) Could not connect to mirrors.tuna.tsinghua.edu.cn:443 (101.6.15.130), connection timed out

W: Some index files failed to download. They have been ignored, or old ones used instead.

因为使用清华镜像连接有错误，所以我现在使用阿里云镜像了。
