So I'm trying to run an update to the tripwire database via
./tripwire --update --twrfile ./report/name.twr as described here as root on my computer but I get these errors (note that --init and --check worked fine):
No protocol specified
QXcbConnection: Could not connect to display :0
Interactive Update failed.
Error: Editor could not be launched.
I'm running Debian 9.1 with KDE. How can I fix this problem?
