J. Félix Ontañón felix.ontanon at podgroup.comHi Harald, you nailed it. The packages were an old custom built with some custom parameters. By just installing the osmocom Ubuntu 20.04 apt repository ( https://download.opensuse.org/repositories/network:/osmocom:/latest/xUbuntu_20.04/) simtrace2 runned perfectly. Thanks.
