Ubuntu 22.04 misses coturn TURN and STUN server package in its system repository. Here’s how to install it via PPA.
Coturn is a free open source implementation of TURN and STUN Server, which can be used as either a VoIP media traffic NAT traversal server and gateway, or general-purpose network traffic TURN server and gateway.
The software package is available in all current Ubuntu releases, exclude Ubuntu 22.04! The reason that the new LTS exclude the package might be a compile issue due to OpenSSL 3.0 does no longer has FIPS 140 mode.
When you try installing the package in terminal, it will output that “E: Package ‘coturn’ has no installation candidate“.
Ubuntu 22.10 development branch has added a patch to fix build the package against OpenSSL 3.0, and here’s an unofficial backport for Ubuntu 22.04 via PPA repository.
NOTE: I’m NOT sure if it’s the real reason that Ubuntu 22.04 exclude the package in its repository. Use the PPA package in your own risk!
