When running the submitubuntu or package command, I get this fatal error:
quickly.templatetools.CantUpdateFile: Build-Depends: debhelper (>= 8), was not found in the file myproject/debian/control.
ERROR: submitubuntu command failed
The debhelper dependency in control is set by quickly itself, if I change it, it is changed back before packaging.
Solved by upgrading, it was indeed this bug:
