Idk if this is the most streamlined way but, you could just fire an automation that snaps a pic, then saves that pic in HA and then use one of the many file synchronizing add ons like Samba or Syncthing to then send that file to your linux box. Im not sure of how you would attatch it to an email directly from HA. That may be possible, I dont recall seeing that and have never looked into it either.

You know that you can get HA notifications that include camera snapshots sent directly to your phone, right?

Apparently you can send emails… so, just make an automation that takes a snapshot when button is pressed, then attatch a copy of that photo to an outgoing email…

I forgot to mention that I don’t have home assistant , my server is already at maximum and I don’t want to add another

I found a code but I don’t know if it can be included and, if so, how.

Would probably have to be prototyped first on the on_image event as a lambda, as image data is available in that event. Problem is that you cannot pause for so long in the lambdas.
