Libpython3.11 problems with Kamailio on Ubuntu 22.04

I run Ubuntu on my desktop and I mess with Kamailio a lot.

Recently I was doing some work with KEMI using Python, but installing the latest versions of Kamailio from the Debian Repos for Kamailio wasn’t working.

The following packages have unmet dependencies:
 kamailio-python3-modules : Depends: libpython3.11 (>= 3.11.0) but 3.11.0~rc1-1~22.04 is to be installed

Kamailio’s Python modules expect libpython3.11 or higher, but Ubuntu 22.04 repos only contain the release candidate – not the final version:

root@amanaki:/home/nick# apt-cache policy libpython3.11
  Installed: 3.11.0~rc1-1~22.04
  Candidate: 3.11.0~rc1-1~22.04
  Version table:
 *** 3.11.0~rc1-1~22.04 500
        500 jammy-updates/universe amd64 Packages
        100 /var/lib/dpkg/status

Luckily the deadsnakes PPA to the rescue!

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get purge kamailio
sudo apt --fix-broken install
sudo apt-get upgrade
apt-get install kamailio kamailio-python3-modules

And done!
