Don't install from apt repository, because the version 0.13.1+dfsg-1 is too low for J-Link probe.
Install PyOCD from pip
pip uninstall pyocdThis will install PyOCD into:
/home/[user]/.local/bin/pyocd
/home/[user]/.local/bin/pyocd-gdbserver
/home/[user]/.local/lib/python3.10/site-packages/pyocd-0.34.2.dist-info/*
/home/[user]/.local/lib/python3.10/site-packages/pyocd/*In Ubuntu, .profile will take care of the PATH, run source ~/.profile to make pyocd command available
