去年把两个PVE集群从V5升级到了V6，都比较顺利。
操作参考[pve]Proxmox Virtual Env集群升级v5到v6。
这周把一个V5的PVE集群升级到V6却遇到新问题，记录下。
该集群有十个节点，原有许可到期，只能改用免费的软件源。为了加快速度，我先把其中一个节点完成了升级，很顺利。主要目的是把相关的deb升级包同步到其他节点。
接下来本该按部就班升级其他节点，却遇到奇怪的故障。

#如果本来就在使用ceph，就不要加这条，按照ceph升级流程去操作，这个pve集群以前安装过过ceph，但是已经删除了，这里顺便跟着升级

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).此时执行apt --fix-broken install会报告同样的错误，各种修改软件仓库地址都一样，最后的办法是强制安装：
代码语言：javascript复制cd /var/cache/apt/archives/
dpkg -i *.deb然后再执行apt --fix-broken install完成修复
最后其中一台还有遗留问题：
