WSL2-Ubuntu22.04下载g++时出现 libc6-dev 软件包linux内核冲突的问题

在WSL2-ubuntu22.04环境下执行

sudo apt-get install g++

出现这样的报错：

the following packages have unmet dependencies:  
libc6-dev : depends: libc6 (= 2.31-0ubuntu9.17) but 2.35-0ubuntu3.1 is to be installed              
			depends: libc-dev-bin (= 2.31-0ubuntu9.17) but it is not going to be installed

问题根源

apt在安装g++时，要从你设定的apt源中获取，然而你设定的源需要执行的ubuntu系统内核版本与当前执行环境的不匹配。

解决方案：

需要根据ubuntu对应的版本进行apt源更换。

查看linux系统的发行版本信息

执行以下命令

lsb_release -a

根据版本对应安装国内镜像源-本文以国内清华源做案例部署
ubuntu22.04
1.备份原先的官方源

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

2.修改sources.list文件内容，先删除文件原来的官方源，添加国内清华源镜像

# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-security main restricted universe multiverse

3.执行以下命令更新源即可

sudo apt-get update
sudo apt-get upgrade

4.等待更新完后再安装g++即可

同上，下面给出对应ubuntu版本的国内清华源，按照上面步骤，修改好source.list文件。
