Approach
The approach of this issue may be change the way the dependencies are uninstalled. But, a more effective and faster way to solve this is changing the order of the execution of the script, by performing the HW check before the dependencies installation.
This should be done carefully in order not to break the natural order of the script, and provoking and undesired behavior (for example, checks the HW in an uninstallation case)

Description
Related: https://github.com/wazuh/wazuh-packages/issues/2660 In https://github.com/wazuh/wazuh/issues/22831, we have observed that, if the system does not verify the hardware requirements, the
lsofpackage and its dependencies are not removed from the system. It is necessary to modify the code to clean the system in this case.Tasks
Verify that the
lsofpackage and its dependencies are removed when the HW checks failed.
