原文地址：https://www.v2ex.cc/224.html

更新的时候控制台会有如下警告提示：

一般PVE更新服务器出现问题会输出以下错误日志：

TASK ERROR: command 'apt-get update' failed: exit code 100

在PVE中出现 TASK ERROR: command 'apt-get update' failed: exit code 100 这个错误提示是由于企业版软件源需要付费(dìngyuè)才可以访问，免费版实际上应该是使用最多的版本。
未订阅用户如果需要更新Proxmox可以使用Proxmox VE无订阅存储库。

Proxmox VE无订阅存储库，pve-no-subscription回购可用于测试和非生产使用。

它不推荐在生产服务器上运行，因为这些软件包并不总是经过严格测试和验证。

顾名思义，没有Proxmox VE订阅密钥需要访问此存储库。

2018.2.6更新：根据研究群里大佬的提醒，Proxmox VE从5.x之后的版本已经是 stretch 了，源还用jessie肯定会失败的，所以本文根据官方wiki文档做了修改，请仔细阅读。

修改 /etc/apt/sources.list

deb http://ftp.debian.org/debian stretch main contrib
 
# PVE pve-no-subscription repository provided by proxmox.com,
# NOT recommended for production use（不推荐用于生产用途）,
 
deb http://download.proxmox.com/debian/pve stretch pve-no-subscription
 
# security updates
deb http://security.debian.org stretch/updates main contrib

然后禁用官方的收费服务器：

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

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

在这一句代码前加个#号注释掉即可。改为以下内容

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

附：Proxmox ve关闭登录时的未订阅弹窗

在5.1版本验证通过提醒：升级到5.1-46版本后，官方已经更改了弹窗JS路径。
根据博友uouuou的摸索后发现，Proxmox ve官方在5.1-46版本之后已经更改了弹窗JS路径。
区别在第一步备份及所编辑的JS路径不同
下面提供两种不同版本的解决方案，请根据自己的版本选择对应的操作。
1、备份原始文件
5.1-46版本之前操作如下

root@pve:~# cd /usr/share/pve-manager/js
root@pve:/usr/share/pve-manager/js# cp pvemanagerlib.js pvemanagerlib.jsbak
root@pve:/usr/share/pve-manager/js# vi pvemanagerlib.js

5.1-46版本之后操作如下

root@pve:~# cd /usr/share/javascript/proxmox-widget-toolkit
root@pve:/usr/share/javascript/proxmox-widget-toolkit# cp proxmoxlib.js proxmoxlib.jsbak
root@pve:/usr/share/javascript/proxmox-widget-toolkit# vi proxmoxlib.js

2、找到这一行（5.1 3rd release在第850行，5.1-49在第352行。版本不一样可能对应的位置不一样，建议自己搜索）:
