I want to run Cartographer in noetic using turtlebot3. But When I run Cartographer Demobag, the error is occured.

================================================================================
REQUIRED process [rviz-4] has died!

================================================================================

Master node OS version is Ubuntu 20.04.6 LTS and, remote PC OS version is Ubuntu 20.04.4 LTS.

I installed Cartographer following https://google-cartographer-ros.readthedocs.io/en/latest/compilation.html#building-installation

I removed Cartographer and reinstalled, but the situation is same.

When I installed Cartographer ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: cartographer: [libabsl-dev] defined as "not available" for OS version [focal] is occured.

So, I solved it by following https://github.com/cartographer-project/cartographer_ros/issues/1726

Now, what can I do?
