Proxmox6升级7.1及更新debian11最简单的方法

国外的服务器升级操作，源部分国内麻烦自行更换。

1、编辑源地址

nano /etc/apt/sources.list

加入下面的源：

deb http://deb.debian.org/debian bullseye main
deb-src http://deb.debian.org/debian bullseye main

deb http://deb.debian.org/debian-security/ bullseye-security main
deb-src http://deb.debian.org/debian-security/ bullseye-security main

deb http://deb.debian.org/debian bullseye-updates main
deb-src http://deb.debian.org/debian bullseye-updates main

保存退出后：

apt update

apt dist-upgrade

然后重启一下就行了。

reboot
