Comment 8 for bug 1473450

I have tested this again, several times. I deployed 6-unit ubuntu charm, twice. Once it worked ok (no issues), once I had the same issue.
I tried repeating with 20 units (as I need to upgrade customer who's running over 100 units), and it failed each time.
I'm adding the log files from the environments as attachment here. There is terminal.log, which is copy-paste output from commands run in terminal, and there is all-machines.log from the bootstrap node.
I have all the other log files archived and can provide them if needed.

There is, however, a workaround for this - first one has to save all the agent.conf files from each unit, and then add apiaddress/apipassword where needed.
