Why did you install from a PPA? What PPA?

Mate is provided by an Ubuntu flavour and available by official
repositories.

http://www.ubuntu.com/download/ubuntu-flavours
  -> https://ubuntu-mate.org/

Actually I don't now Ubuntu Mate myself, but assuming it should not be
up to date for you, then you perhaps should consider to use another
distro. If you just want Mate, provided by Ubuntu, how ever up to date
it might be or not, then simply use/install Mate from official
repositories.
