Do we really need a custom package? Can we just use the one provided by Ubuntu 16.04?

[Dmitry Burmistrov (dmburmistrov)]

We should make a decision.
1) fix dependencies for mysql-server-wsrep-5.6 (to accept mysql-client-5.7, I think they won't conflict)
2) Go to 5.7 (as Ubuntu did) and keep strict dependencies
3) Provide 5.6 to satisfy dependencies (if №1 or №2 options are not acceptible)

Hi, all, I meet a problem like this, I am integrating mysql-wsrep-server on Ubuntu16.04(xenial), but apt-get install fails, I get these via https://launchpad.net/~mysql-ubuntu/+archive/ubuntu/mariadb-10.1/+build/9360371 , but the dependency makes me crazy, mysql-wsrep-server-5.6 needs mysql-wsrep-client-5.6 which needs libdbd-mysql-perl and mysql-wsrep-common-5.6, but libdbd-mysql-perl auto install mysql-common-5.7 which mysql-common conflicts with mysql-wsrep-common-5.6, I try to apt-get --purge remove mysql-common-5.7 which remove libdbd-mysql-perl, so I integrating mysql-wsrep-server on xenial fails, do I have to use mysql-wsrep-server 5.7 on xenial? if so, where can I get mysql-wsrep-server 5.7 ?

A decision is being awaited, fixed to confirmed as incomplete seems a bad fit
