PVE刚安装好，如果不更换国内的源，有些软件下载会很慢，太难受了，那必须得换掉。
首先注释掉这个文件内的所有内容：
vi /etc/apt/sources.list.d/pve-enterprise.list
下载中科大的GPG KEY
wget https://mirrors.ustc.edu.cn/proxmox/debian/proxmox-release-bookworm.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg
使用Proxmox非企业版源
echo "deb https://mirrors.ustc.edu.cn/proxmox/debian bookworm pve-no-subscription" > /etc/apt/sources.list.d/pve-no-subscription.list
将Debian官方源替换为中科大源
sed -i 's|^deb http://ftp.debian.org|deb https://mirrors.ustc.edu.cn|g' /etc/apt/sources.list
sed -i 's|^deb http://security.debian.org|deb https://mirrors.ustc.edu.cn/debian-security|g' /etc/apt/sources.list
替换Ceph源
echo "deb https://mirrors.ustc.edu.cn/proxmox/debian/ceph-quincy bookworm no-subscription" > /etc/apt/sources.list.d/ceph.list
替换CT镜像下载源
sed -i 's|http://download.proxmox.com|https://mirrors.ustc.edu.cn/proxmox|g' /usr/share/perl5/PVE/APLInfo.pm
