How not to update some programs on Ubuntu 16.04 VPS?

Question

System administration

I don’t want to update the muscle at the vpsk - there are always problems, then for half a day I pick something and fix it, how to remove it from updates? Do not criticize - it's necessary, now there is a lot of work and there is no time yet to raise a whine that has fallen - and a dozen business sites work on it (and moreover, it is stable).

Answer 1

apt-mark hold mysql-server

Answer 2

do it easier - do not update anything at all.
many systems hang like that.
