@lix19937 galactic is already E.O.L, can you try supported distribution instead? see more details for https://docs.ros.org/en/rolling/Releases.html.

the following is humble example, and that works no problem.

root@tomoyafujita:/# apt install ros-humble-rosbag2-storage-mcap
...

root@tomoyafujita:~# source /opt/ros/humble/setup.bash

root@tomoyafujita:~# ros2 bag record -s mcap -a

i think we can close this issue, but please feel free to keep if you have any problems with supported distribution.
