Description

While working on https://github.com/wazuh/wazuh-packages/issues/1422, I noticed a strange behavior in the Wazuh packages offline download: the indexer package could not be downloaded, and it takes too much time to be completely downloaded.

After debugging the behavior, I found that the Wazuh indexer package downloaded was interrupted because of the --max-time 300 option specified in the curl command. This provokes another retry to download the package, and then, another interruption:

> bash wazuh-install.sh -dw rpm -v

Do you want to remove the ongoing installation?[Y/N]

Notice that the indexer package is only 70% downloaded, and 60% downloaded. The indexer package is the largest package of Wazuh, taking 1GB approximately.

:bulb: We should consider incrementing the --max-time 300 parameter to allow downloading the packages with slow internet connections.
