The pi is running 4.19.50-v7+ right now, so this should be the correct
translation:
pi@picnc:/media/pi/workpi120/buildbot/linux-5.1.14 $ sudo apt-get
build-dep linux-image-4.19.50-v7+
Reading package lists... Done
E: Unable to find a source package for linux-image-4.19.50-v7+
For every step fwd, 2 back...
