How To Fix signal-rr-recording: command not found in Ubuntu / Debian / Kali Linux / Raspbian
In Ubuntu signal-rr-recording is provided by rr package.
rr is:
rr allows application executions to be recorded and then replayed with gdb as many times as desired.
This allows intermittent, or complex to reproduce, bugs to be captured and then debugged at leisure. Replays are deterministic, always identical from one run to another.
rr is incompatible with ptrace hardening, and currently only supports Intel CPUs with Nehalem or later microarchitectures, and some Zen CPUs. The amd64 package supports debugging amd64 and i386 binaries.
To fix this problem, we can install more using the command below.
sudo apt-get -y install rr
This command might take some time to finish depending on your machine internet connection.
You can also use apt command to install rr.
sudo apt -y install rr
Or if you have aptitude installed you can use the following command.
sudo aptitude install rr
