Hello,
I'm using flirc-usb with the RPi5 running Ubuntu 22.05. Unfortunately, the latest version of Debian and Ubuntu use libreadline8, rather than libreadline6, so apparently the script to add the repository fails. I've tried running the generic Linux versions, but I get the message "-bash: /usr/bin/flirc_util: cannot execute: required file not found". I thought I had manually chased down all the repositories, but apparently not. Is this message from missing libreadline6? Seems like a flatpak or snap may be in order, if the devs can't keep current.
