workflow question

[Jack]

I don't know why I'm having problems with this, but how does one keep a 
fork updated with the source?  All my searching points to mirroring, but 
that seems to be restricted to administrators in KDE's GitLab.  Since I 
do have commit privs to the main repository, I know I can just create a 
new branch, work there, push it to invent.kde.org and create an MR 
there.  I know there is a convoluted way to pull from upstream to your 
local clone, do work, push to your fork and create an MR, but assuring 
no merge conflicts seems to require great care in doing things in the 
right order.
