root@xuyuquan:~# apt-get update
Err:1 http://ftp.debian.org/debian bullseye InRelease
  Temporary failure resolving 'ftp.debian.org'
Err:2 https://enterprise.proxmox.com/debian/pve bullseye InRelease
  Temporary failure resolving 'enterprise.proxmox.com'

1、vi /etc/apt/sources.list.d/pve-enterprise.list
注释掉

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

2、

vi /etc/apt/sources.list

deb http://download.proxmox.com/debian stretch pve-no-subscription

3、

echo "deb http://download.proxmox.com/debian/pve stretch pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list

4、

wget http://download.proxmox.com/debian/proxmox-ve-release-5.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-5.x.gpg

这步还会出错：error：wget: unable to resolve host address ‘download.proxmox.com’
5、解决：echo "nameserver 1.1.1.1" >> /etc/resolv.conf
6、apt update && apt dist-upgrade 成功
