coturn for Ubuntu Jammy (22.04 LTS)

Today I had to install coturn on Ubuntu 22.04 (Jammy Jellyfish). It doesn’t have package available because of a bug. But there’s a solution on the bugtracker, so I decided to build my own package. It has been a while since I last did it, so here are the steps for reference:

1. Install Ubuntu Jammy (I had it installed anyway)
2. Make sure you have deb-src sources for both jammy and impish in sources.list
3. Install tools: apt-get build-dep dpkg-dev quilt build-essential
4. Install build dependencies: apt-get build-dep coturn
5. Get sources: apt-get source coturn
6. Patches for the package are managed using quilt
7. quilt push -a
8. quilt new jammy.patch
9. quilt add src/client/ns_turn_msg.c
10. $EDITOR src/client/ns_turn_msg.c and change the one line
11. quilt refresh
12. quilt pop -a
13. dpkg-buildpackage -us -uc
14. dpkg -i coturn*.deb
15. apt-get -f install

This produced the quilt patch below:
