weirdly, installing serialosc from the PPA basically works for me with occasional segfaults. sometimes
serialoscd starts and sometimes does not running raspbian stretch lite here.
btw, i’m installing serialosc by first installing
dirmngr to fetch the repository public key (it’s not installed by default on stretch lite). the package still crashes, so do not try this at home!
sudo apt-get install dirmngr
then getting the public key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys DD9300F1
then adding the repository:
sudo echo "deb http://ppa.launchpad.net/artfwo/monome/ubuntu artful main" >> /etc/apt/sources.list.d/monome.list
sudo apt-get update
sudo apt-get install serialosc
next thing i’m gonna try is to make a PPA build with debug symbols so it can be debugged properly. hope that works!
