What is wrong?

I’m running Trinity as root via Supervisor. I’m using sudo -i to elevate to root with root environment. I then run trinity attach and the first thing that I notice is that it starts logging to my user account home directory /home/chase/.local/ instead of /root/.local/ and none of the commands seem to work.

Is this due to how I’m running Trinity and trying to attach with sudo -i? or something else?

Maybe trinity attach should directly print out a warning if it doesn’t find the ipc pipes

👍 Probably even just exit out with a failure message if the pipe is missing

@MysticRyuujin Thanks again for reporting this. I opened up #959 to improve on the user experience for this case.

I’m closing this issue here. If you feel there’s anything unaddressed please feel free to comment and reopen.
