This set of minor changes to the Dockerfile allows using visualize_franka.sh with Jazzy, to avoid incompabitilies in a Jazzy-based setup.
Jazzy has UID/GID 1000 already used by the
ubuntu
user, so I implemented a use existing group or create new group logic, same for the UID. For details, seehttps://techoverflow.net/2025/01/12/shell-logic-how-to-create-user-group-if-no-user-group-with-that-uid-gid-exists/
I only tested scripts/visualize_franka.sh, and only with
arm_id:=fr3
. All tests were performed with UID=1000 & GID=1000 on Ubuntu 24.04.
