On my Raspberry Pi I'm using the 64-bit Raspberry Pi OS from here.
Now I would like to use
rinetd on it. Unfortunately the
rinetd package is hopelessly outdated and is for example missing IPv6 support. The latest version of
rinetd is 0.73 but the Raspberry Pi OS package contains version 0.62 from 2017.
I saw on Launchpad that there seems to be a 0.73 package available for the next Ubuntu.
Can I somehow force the Raspberry Pi to install that package? Since it's a very simple tool with essentially just an executable, a systemd unit file and a manpage I think there is a decent chance that it could run.
As an additional complication, when I try to list the files for the arm64 build on packages I get an HTTP 500. Does that mean the ARM build failed? ARM builds are not properly listed on packages, they are on ports,
rinetd is here: http://ports.ubuntu.com/pool/universe/r/rinetd/rinetd_0.73-0.1_arm64.deb
