No minions matched the target. No command was sent, no jid was assigned<Salt-stack>

Question

I installed saltstack and added one minion to master. I get the command output as below

$ salt-key
Accepted Keys:
xxxx.abcd.com
Denied Keys:
Unaccepted Keys:
Rejected Keys:

but when I hit the

$salt \* test.ping

command. I get response as

No response from minion

Not very sure what is going wrong.

Answer 1

I found the solution for this:

seems that minion was having an old copy of the public key of master and hence handshake was not happening. steps of resolution:

1. go to folder /etc/salt/pki/minion/ on minion
2. remove master_public file
3. restart the minion 

now test.ping responds as required

Answer 2

These are two issues with different reasons.

1

No minions matched the target. No command was sent, no jid was assigned.

This happens when you targeted minions which are not registered on the master.

In other words, none of the minions is listed under Accepted Keys: of salt-key command output.

2

No response from minion

This happens when you targeted minions which are registered but they do not respond.
