Unable to install wine in ubuntu mate 18.04.

Do you want to install wine or PlayonLinux?
Have you tried opening a terminal window and executing the command

apt install wine

or

apt install playonlinux

(depending on what you want)?

Thanks for the response.
Tried your suggestion and got:

Package wine is a virtual package provided by:
  wine-stable 3.0-1ubuntu1
  wine-development 3.6-1
You should explicitly select one to install.

E: Package 'wine' has no installation candidate
************************************************
What should I do next?
