Hello All,

I tried apt --fix-broken install and apt --fix-missing install Nothing seem to be working.
I also checked ROS2 repositry URL deb [arch=amd64 signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu jammy main
Noting seems to be working. Any help would be appreciated.

Best Regards

Hey @raghav.nandwani Have you tried running sudo apt-get update before running sudo apt install...?

Yes tried everything. But now it is solved by installing ros as well as colcon and other packages from source.
