Sury repository is pushing possibly unwanted upgrades

But if keep the repo, won’t the Sury packages always appear newer than Debian’s?

Thank you very much again. Oh, and did I tell you that having my own server at home, owing to Ynh, is something for which I’m very grateful, everyday?

PS. Not sure I would be able to help for the phpenv solution, but I know that there are other ways to help: I will consider them very carefully.
