Hi,

While I tried running a bench update --upgrade on one of the client machines, I got this following error. Looks like the upgrade got completed but ended up with this error.

Your bench was upgraded to version 7
supervisor.conf already exists and this will overwrite it. Do you want to continue? [y/N]: y

Hi Experts,

Im trying to add another site and app to my server - self hosted on digital ocean. I have created the site and app successfully and installed to the site successfully, but when I try to run : bench setup nginx I get this error:

Am I missing something - I tried this on my VM and all worked out fine. So not sure what I done wrong.

Im running v7

Anyone with some feedback will be greatly appreciated.
