devsec.hardening.mysql_hardening - Operation not supported on ubuntu 22.04

Description

When applying mysql_hardening role on a ubuntu 22.04 host with mariadb 10.6.11 I got

Hi @markuman,

can you please do the following?

ls -lsah /etc/mysql/*
lsattr -R /etc/mysql/*

and put the output here?

I guess it's got something to do with symlinks..

Also do you run the playbook as root?

test playbook on a hetzner vm ubuntu 22.04 as user root

Thanks, can you do the same on /etc/alternatives/my.cnf, please? Meanwhile I'll get myself a VM to test.

@rndmh3ro I'm getting a similar error on Ubuntu 22.04 with MySQL 8.0.34:

Exception: Error while setting attributes: /etc/mysql/my.cnf.68739.2023-08-22@15:36:39~: Operation not supported

Here's my output from what you requested from the original issue creator:

I'd guess it has something to do with a command trying to use the output of the lsattr command, not expecting the output to be lsattr: Operation not supported. But I'm not at all familiar with what's going on in this role.

[rndmh3ro]

The role at this task changes the my.cnf and creats a backup-file, in your case /etc/mysql/my.cnf.68739.2023-08-22@15:36:39~.

This seems to be a known bug in Ansible: ansible/ansible#76727

And a PR: ansible/ansible#78707

If anyone wants to try the PR out and comment on it, maybe it would help in getting it merged.
