```console
apt-get install apparmor
```
#### Kata Containers
The 23.0 branch brings support for alternate containerd shims, such as `io.containerd.runsc.v1` (gVisor) and `io.containerd.kata.v2` (Kata Containers).
When using the Kata Containers runtime, exiting an `exec` session stops the running container, and hangs the connected CLI if a TTY was opened. There is no mitigation at this time beyond avoiding execing into containers running on the Kata runtime.
The root cause of this issue is a long-standing bug in Moby. This will be resolved in a future release. Be advised that support for alternate OCI runtimes is a new feature and that similar issues may be discovered as more users start exercising this functionality.
