pve换源

1.首先备份一下原始源并更名

mv /etc/apt/sources.list /etc/apt/sources.list.bak

2.打开这个文件

nano /etc/apt/sources.list

输入以下源：

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm main contrib non-free non-free-firmware

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-updates main contrib non-free non-free-firmware

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-backports main contrib non-free non-free-firmware

deb https://security.debian.org/debian-security bookworm-security main contrib non-free non-free-firmware

3.打开国内企业源列表

nano /etc/apt/sources.list.d/pve-no-subscription.list

输入：

deb https://mirrors.tuna.tsinghua.edu.cn/proxmox/debian/pve bookworm pve-no-subscription

4.屏蔽企业源

nano /etc/apt/sources.list.d/pve-enterprise.list

改为：

#deb https://enterprise.proxmox.com/debian/pve bookworm pve-enterprise

5.禁用ceph源

nano /etc/apt/sources.list.d/ceph.list

改为：

#deb https://enterprise.proxmox.com/debian/ceph-quincy bookworm enterprise

6.最后更新一下

apt-get update

能正常下载更新就没问题了，然后PVE后台点更新，如下图：有更新的点升级，完成reboot重启即可；

这里需要说明一下的是，你PVE的DNS最好别乱填或者填错，我用的是阿里云的公共DNS223.5.5.5这个地址，还有114.114.114.114，再就是路由器的网关地址，贼好用。
