Eventually the repository for MariaDB stops working, for some reason.

Since you’re working with VPSs, why don’t you clone an existing VM with EE installed and running? Not the best solution, but it would allow you to move ahead.

I am using google cloud. How can i clone this instance

Unfortunately I can’t help with Google Cloud. Perhaps you should ask Google for support (no pun intended).
