[SOLVED] Can't create cluster. Could not create /etc/corosync/authkey: No such file or directory.

Hello, I just upgraded from 7.4 to 8, everything went ok until now. I have 2 nodes at home, which I use in a cluster. The node I am having trouble with is the one I upgraded (both are, but the other one I had to do a fresh install).

I followed every step on the wiki and it all went fine, just a warning about quorum, as the cluster was composed of 2 nodes instead of 3. After upgrading I can no longer create a cluster. Even if I create the cluster on the second node I can't join the one not working fine.

P.S: It used to exist a cluster, but as I had to reinstall proxmox on the other node due to messing up the upgrade, I deleted it to start all over. Maybe that was the mistake? May I have messed up some things on the node so I can't create/join a cluster?

Here's the output:
corosync-keygen: Could not create /etc/corosync/authkey: No such file or directory
