on the repo there only seems to be copies of this for Ubuntu yacketty (16.10) and Ubuntu zesty (17.04). Both of these are end of life. Is there supposed to be support for Bionic (18.04)? 

Secondly, they are tagged with the mariadb version number. Are they supposed to work across versions because not every version of Mariadb is represented?

Thirdly is there any reason I can't pull the code from Gidhub and compile it myself?

Many thanks in advance
