Hi! Thank you for your fork of VestaCP!
Is is possible to make Hestia installation without adding any external repositories? I see no reason why to force the Ondrej PHP PPA repository (and others) to be installed. In terms of server security and stability, this is a big minus.
For example, Ondrej PHP PPA repository can raise current version of the PHP during an upgrade without any notice, and this will lead to the inoperability of sites.
Also, if custom PHP modules are used, changing the version will cause the server to fail.
