hi @saad2121 Thank you for sharing the details of the issue. It seems that the gmapping package might not be installed or there may be an issue with the installation.

Please try reinstalling the gmapping package by running the following command:

sudo apt-get install ros-noetic-gmapping

After reinstalling, relaunch the SLAM process and see if the issue is resolved. Let us know if you continue to encounter problems.
