Running a wallet/masternode on linux here and I have a question.
It looks like the latest 'sentinel' is expecting a X window to be present.
Xlib.error.DisplayNameError: Bad display name ""
Is there a workaround?
Have you seen my other reply?
Are you running it headless (without graphical interface)? If so, you might try running it through xvfb-run (apt-get install xvfb-run first)
xvfb-run ./sentinel-lin64
