Can't find how to remove project (im new on lauchpad)

We can remove your projects, but I don't understand your comment about not fitting into Launchpad's ideology. Launchpad is perfectly happy for you to have multiple repositories, and there's no reason I know of why you'd have to construct a separate branch just for Launchpad. Could you explain what you're trying to do and what's going wrong?

If you still want to remove the projects, then please remove https://code.launchpad.net/~pk+nw/lapps/+git/LAppS first (which you should be able to do yourself).

My apologies, I'm totally new to launchpad. I need to create 1 package from 5 repositories. I do not need separate packages for the supplementary libraries (4 of them), which are header-only (3 of them). These supplementary libraries are useless on their own.
One of those repositories is external (LibreSSL), and I do not want to maintain package for LibreSSL. I want to use github as a main CVS, and launchpad only for PPA. So I'll bump all the libraries of specific version into one repository to have a consistent PPA.
Does it makes any sense? Or there is a way to avoid supporting/maintaining 5 repositories instead of 1 other then I described?

Btw thanks for the answer. Main repository is removed. Apparently I need to delete separate project for supplementary library https://launchpad.net/itclib. How?

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

The two projects in question are gone now.

Projects and PPAs aren't tightly linked; you can perfectly well have many projects that feed into a single PPA (either manually or using source package recipes). In general, if you're relying on repositories of code that you didn't write, we recommend using those as-is rather than importing them as subtrees of another repository, which will be a maintenance burden for you down the road. Of course for code you did write you can organise it in whatever way is most convenient for you.
