How to reset all SSH settings to default on Linux?

Question

SSH

I welcome everyone. Setting up ssh because I train a lot, then it becomes necessary to reset the program settings, or rather their default configuration.
Now, in order not to mess up what I did wrong or right in the ssh server config, I want to delete everything and reconfigure it. How can I remove all settings related to SSH on Mint to be sure that I now have everything by default?
Maybe for all Linux programs there is a simple one algorithm ...?

Answer 1

apt purge remove package with configs

Answer 2

now I checked it again, it seems that all settings are deleted through the purge program, I just had a file created by ssh_conf, this is most likely my self-made file, so it was not deleted. the standard one is called sshd_conf and so it was removed and reinstalled.
