I want to test LWT in Scylla DB by jespen

I run this Jepsen test on the virtual machine, and my configuration is Ubuntu 20 04，docker version is 20.10.12 and docker-compose version is 1.25.0.I tried two different docker containers.
1、tjake/jepsen
When I use it, report error：STDERR：E：Command line option --allow-downgrades is not understood.

2、jepsen-io/jepsen/docker
When i use it , report error：ERROR：Command exited with non-zero status 1 on node n1：sudo -S -u root bash -c "cd/；server scylla-server start“。STDERR：Job for scylla-server.service failed because the control process exited with error code

This looks like DB nodes start fail.
Then I try add up aio-max-nr.
like this echo 16777216 >/proc/sys/fs/aio-max-nr Successfully started DB nodes
But later


I tried sudo apt-get，but it don't work.

How can I handle these errors so that I can run tests？

Trying to use Jepsen to test the latest version of Scylladb (e.g., v5.0.0). However, I always get the following error during setup and have no idea how to fix it:

Begin with this warning:

===== Using optimized driver!!! =====
INFO [2022-08-02 13:09:29,858] jepsen node n2 - scylla.client n2 not yet available, retrying

And finally, get this error:

ERROR [2022-08-02 13:10:14,676] main - jepsen.cli Oh jeez, I'm sorry, Jepsen broke. Here's why:
clojure.lang.ExceptionInfo: throw+: {:type :jepsen.db/setup-failed, :msg :await-open-timeout, :node "n4"}

Could you give some suggestions to fix this error?
