Aria config minion is automatically denied by the salt master after upgrading master

Products

• VMware Aria Suite

Issue/Introduction

Ater upgrading the master, Aria Config minion is automatically denied by salt master.  It shows as both "Denied" and "Unaccepted"

Running salt-key -L shows something similar to the following output:

[root@salt-master ~]# salt-key -L
Accepted Keys:
salt-master
Denied Keys:
salt-minion01
Unaccepted Keys:
salt-minion01
Rejected Keys:

Removing the key and reaccepting does not resolve the issue.

Environment

Aria Automation Config (AAC) 8.16.x and lower
Salt 3006.7 and lower

Cause

Caused by a new line not being cleaned up in minion keys, which is resolved in 3006.8

Resolution

Upgrade the salt-master and minion to salt 3006.8 or higher (Long Term Release version 3006.9 is recommended) as per the documented Install Directions:
https://saltproject.io/blog/salt-project-package-repo-migration-and-guidance/ 

After upgrading the salt-master and the affected salt-minion, while the salt-minion is stopped, delete the minion keys from the master:

salt-key -d minion_name

Start and enable the salt-minion service:
systemctl start salt-minion 
systemctl enable salt-minion

The check keys on the master:
salt-key -L 

Verify that it only comes in as "Unaccepted" this time

Run this to accept:
salt-key -a minion_name

Verify that it is now accepted:
salt-key -L
