Restart resolved

How was the upgrade performed, and how can this be reproduced. Need some more information about the process used to validate this issue.

[Joe Guo (guoqiao)]

I checked the code, while `upgrade-charm` hook is triggered, the charm just remove `grafana.installed` flag, which will trigger `install_packages`. In there, the code doesn't consider the situation of re-install and upgrade, which may need a restart. Of course the apt or snap package manager may do that, but not guaranteed. It will be better if the code can check the current service status and do a restart if necessary.

Not sure.. this was filed 2 years ago and I don't even remember what customer's stack I was working on. Maybe there's a record in the bootstack salesforce tickets, but I don't have access any more.

Hi Tejeev,
thanks for your reply, in this case I will change the status back to Incomplte for now until we have further issue.
