Hello, We are in a weird situation where we don't say we support MariaDB but "the latest MySQL version of stable Debian repository", which is currently... MariaDB [1]
So we need to update our strategy about this fact. I am currently setting up a server with debian 9 (stable) and I don't know if I should install MySQL from the Oracle repository our continue with the standard debian package (MariaDB). On my side, I am not against aligning ourself to debian. Basically, all users installing XWiki with our Debian packages are using MariaDB for a year now [2], and we never encounter any problem so far. Thanks, [1] https://packages.debian.org/stretch/default-mysql-server (dep: mariadb-server-10.1) [2] https://www.debian.org/News/2017/20170617.en.html Le lun. 12 nov. 2018 à 18:54, Thomas Mortagne <thomas.morta...@xwiki.com> a écrit : > Indeed mysql-server package (version 5.5.9999) leads to > mariadb-server-10.1 in current stretch repository. > > What is surprising is that this is not the case for sid which is more > or less supposed to be the future.
