Building from GIT repo
No series file found fatal: not a git repository: /home/killy/tde/2_build/build/applications/multimedia/k3b/../../../../.git/modules/main/applications/multimedia/k3b fatal: not a git repository:
For various reasons I use my own build script, so I do not know if I am supposed to comment at all, but in this case it is looking for .git in the wrong directory.
Indeed, wrong user process. You are building from the build folder, not the git folder. When things are setup from git to build folder by build_module.sh, the debian patches are applied once, then the series file is removed to avoid reapplication faults. If you try to make your build folder the git folder, you will get something like the above.
I suggest you re-read the readme file a second time and confirm your setup is correct. It may be a good idea to redo it from scratch, now that you have got a first exposure to the process.
