debian stretch upgrade - mariadb removed libmysqlclient.so.18 - how to get it back?
as a temporary fix, I installed the deb for libmysqlclient18 directly from here: https://launchpad.net/ubuntu/xenial/amd64/libmysqlclient18/5.6.25-0ubuntu1
a more official answer would be welcome.
I fixed this error with ln -s /usr/lib/x86_64-linux-gnu/libmariadb.so.2 /usr/lib/x86_64-linux-gnu/libmysqlclient.so.18
The libmariadb.so.2 comes with the libmariadb2 package.
