I am running ROS Noetic on Ubuntu 20.04.3 LTS.

I cannot run rosbag play or rosbag record. It was working perfectly last week, but it ceased to work this week. I have tried reinstalling using apt install ros-noetic-rosbag, but that didn't help. The weird thing is rosbag check and rosbag info work pretty well:

rosbag check flight_2022_02_21_23_02_03.bag
Bag file does not need any migrations.

I have suppressed the topic names from rosbag info so this thread isn't too long, but this is the header in it:

rosbag info flight_2022_02_21_23_02_03.bag

The following happens when I try rosbag record or rosbag play:

Record:

rosbag record -a -O example.bag
Usage: rosbag record TOPIC1 [TOPIC2 TOPIC3 ...]

rosbag: error: Cannot find rosbag/record executable

Play:

rosbag play flight_2022_02_21_23_02_03.bag
Usage: rosbag play BAGFILE1 [BAGFILE2 BAGFILE3 ...]

rosbag: error: Cannot find rosbag/play executable

I know that the problem isn't with the bag, as a coworker was able to play that same bag. I also tried other bags that I could play before, but I can't play any bags whatsoever now. I have noticed that the error was once observed by one user, but there was no solution anywhere that I could find (that user was supposed to open a question in this forum, but I wasn't able to find one).

Here is what I get from the following commands:

Find rosbag:

Rospack find:

rospack find rosbag

Any ideas in how I can fix this without having to format my laptop? =)

I was just able to find the solution, and I hope this will help others in the future. The issue is that I had ros_comm i
