Just wanted to know the way to generate ssl for my localhost using Ubuntu 20.04 with installed Xampp. I wanted to use the Apache that comes with the Xampp (which means I don't have the external Apache installed via apt. I also have used virtual host instead of the native localhost:port url.

I am having a bit of a hard time since the word Ubuntu + Xampp doesn't generally coexist on the forums that I have searched. They are basically Ubuntu + external Apache or Windows + Xampp.

I tried some things using those forum tips but I ended up with chrome having this error

even though I already enabled Allow invalid certificates for resources loaded from localhost. I also tried clearing Chrome's cache but nothing really made any difference.

Would really appreciate everything for your help. Thank you.
