Writing from Oslo , I back Doug Chadwick who writes "The dish is also known in Norway, where its name is 'lapskaus'".It is served / eaten regularly in Norway especially in winter.
Very much the same origins as Irish stew which was a poor-mans dish,and not the one loaded with meat as one generally finds in todays so called Irish Pubs scattered throughout the world.

In the 80's I was invited to a Liverpool couple's apartment ( in Holland where they were working at the time) to eat Everton Scouse.
(For non-British people Everton is a district of Liverpool) .
I can only say it was the nearest I have ever come to eating Bulldogs spew - as in Vomit (not stew).
