How do i recover from a botched database upgrade
I am running an Ubuntu 14.04.2 server on my digital ocean droplet. I am also running owncloud (current release is 8.0.3 but i was a point release behind...8.0.2 maybe). i was also a bit behind on updates so i ran apt-get upgrade this morning and i was faced with the option of upgrading my mysql server to mariadb. i read the box which told me mariadb is a drop in replacement to mysql so i clicked yes and thought everything would be fine, but it isn't. now the database daemon wont even start AND i have no owncloud now. Can anybody help me...can you point me in the right direction for information? Thanks.
