I currently have no real solution to this problem. But a similar problem we encounter with PySide2, where we had to explicitly set an environment variable QT_API.

However, there seems to be a general problem with the display qt.qpa.xcb: could not connect to display; Could it be that you are executing the labeler in a virtual machine or a docker that might cause the problem?

ghost commented 2 years ago

@jbehley Yes. I was running on it with a docker. When I try to build it without virtual machine or a docker, I continuously fail to build glow. Could you take a look?
