Hi @kalkimann ,

Which ROS distro are you using in ROSDS?

  1. on Ubuntu 20.04 in virtualbox
    sudo apt install ros-noetic-desktop-full

Got the posted Error message.
It is not ROSDS, but would appreciate your input.
Thanks

Resolved via help from the following page: there is a python script here called fixros.py

roscore runs, BUT for some reason the error persists and prevents installs:
The following packages have unmet dependencies:
python3-rosdep-modules : Depends: python3-rospkg-modules (>= 1.3.0) but it is not going to be installed
Depends: python3-catkin-pkg-modules (>= 0.4.0) but it is not going to be installed
Depends: python3-rosdistro-modules (>= 0.7.5) but it is not going to be installed
Conflicts: python3-rosdep2 but 0.18.0-1 is to be installed
ros-noetic-rospack : Depends: python3-catkin-pkg-modules but it is not going to be installed
ros-noetic-rqt-gui : Depends: python3-rospkg-modules but it is not going to be installed
ros-noetic-rqt-robot-monitor : Depends: python3-rospkg-modules but it is not going to be installed
E: Unmet dependencies. Try ‘apt --fix-broken install’ with no packages (or specify a solution).

Fixed by :slight_smile: sudo dpkg -P --force-all PACKAGETOREMOVE etc. from the "Stuck in the loop" article
