It seems to be somewhat similiar to wazuh/wazuh#22122 - but I haven't found a solution there.

To Reproduce
Steps to reproduce the behavior:
Call sudo bash wazuh-install.sh -a on Ubuntu 22.04
Latest apt update and upgrade has been done.

Expected behavior
An all in one installation as described here: https://documentation.wazuh.com/current/quickstart.html

Additional context
I also posted on Slack to see if anyone experienced this https://wazuh.slack.com/archives/C0A933R8E/p1718361281257639

EDIT 2❗Executing CIS Build Script L1 Server kills the wazuh-indexer with the described error.

EDIT 1 ❗It appears that the problem occurs once the CIS Build script has been executed.
I have setup a new Ubuntu 20.04 server and installed the all-in-one package. It worked.
After I executed the build script from CIS for server L2 the indexer fails to start.

The output after applying CIS build script Server L1:

Hi @HachimanSec

We have experienced problems during the installation of Wazuh Indexer if the Operative System has the noexec flag enabled on the /tmp folder (see wazuh/wazuh-packages#1539). I think this could be the cause of your problem. Another user posted a workaround. It's worth trying. We have already fixed the issue for 4.9.0.

The warnings messages are known and expected, there is nothing wrong there.

This was my exact problem, as the server was pre-hardened, all of the tmp filesystems have nodev,noexec flags on mount.

[AlexRuiz7]

We are working on that on #501
