That’d do it. The venvs used for the package build inherit the system environment for $reasons so a conflicting package in the system environment will break the build.
you should ask radarbox to isolate their mlat-client better.
edit: I pushed a change to the dev branch that may help, can you try again?
It is not fault of Radarbox24. The mlat-client package provided by Radarbox repository is numberd quit differently, it is version number 1:0.2.13+deb11 (Please see screenshot below).This version number does not tally with version number 0.2.13 built by piaware package.
Radarbox24 have not yet released their mlat-client for debian12 Bookworm. Their supplied version is for debian11 Bullseye, and it does not function properly on Bookworm. Terefore I built version 0.2.13 from source code right on Bookworm, and it worked ok with RB24. I did not realise it will create conflict with package built process of piaware.
The issue is that it’s a globally installed python package. I didn’t anticipate that this problem would happen when providing debian packaging for mlat-client; my assumption was that forks would take care to not conflict with the upstream package, by for example renaming the package, but that has not happened in this case.
I’m considering removing the separate debian packaging of mlat-client entirely since it’s really a starting point, not a fully fledged compatible-everywhere thing. You would need to install via the Python packaging tools (presumably in a venv, or deal with the consequences!), not build a Debian package. Would this break anything of yours?
I dont build & install mlat-client for anything except in case of Radarbox24 as they have not yet released their package for Bookworm. Once they release it, I wont need to build it from source code.
Anyway, this only affects the building of piaware package, and NOT the normal operation of piaware.
can you try the latest dev branch to see if it helps?
OK, will try new dev branch now
thanks for your help in this topic. Today my new 64 bits SDcard was taken in to production,

piaware 9.0.1 was installed from the repo, seems to be running fine. Mlatclient got created via wiedehopf his repo. For adsbexchange there is a python dependency not correct, because this is loaded within an virtual environment you need to edit the install script. When you edit the script and replace the adsbexchange/mlat-client repo for wiedehopf his mlat repo, its working fine.
graphs1090 needs to be exported with the XML’s because of the 32bit to 64bit architecture change. Its described below in the guide.
For Radarbox24 feeder, I now tried to use mlat-client (which was build by adsbfi in virtual environment) This mlat-client works perfectly well for adsbfi-mlat, but FAILED when used for Radarbox24 feeder.
STEP-1: Located mlat-client built by adsbfi in venv
STEP-2: In file /etc/rbfeeder.ini, changed mlat command to use mlat-client from adsbfi venv instead of from /usr/bin/
STEP-3: Restarted rbfeeder and checked status / logs. FAILED

SOLVED by removing /usr/bin/python3.11 from mlat_cmd in /etc/rbfeeder.ini
Changed from:
mlat_cmd=/usr/bin/python3.11 /usr/local/share/adsbfi/venv/bin/mlat-client
To:
mlat_cmd=/usr/local/share/adsbfi/venv/bin/mlat-client
mlat_cmd, the mlat-client started working OK for Radarbox2 feeder using mlat-client built in venv
