I run an ADS-B monitoring station using RTL-SDR USB dongles. Normally people do this with Raspberry Pis but I have a perfectly good AMD64 box that runs 24/7.
These are the new .deb packages for this version:
http://repo.feed.flightradar24.com/linux_x86_binaries/fr24feed_1.0.34-0_i386.deb x86
http://repo.feed.flightradar24.com/linux_x86_64_binaries/fr24feed_1.0.34-0_amd64.deb amd64
I run these in a podman (docker) container. fr24feed failed to load because CAP_SYS_NICE was not enabled on the container.
You can add the capability to the container or remove the capability from the /usr/bin/fr24feed binary using the instructions here: https://gitlab.alpinelinux.org/alpine/aports/-/issues/11992. Doing either of those options will allow fr24feed to start up.
