Missing Data After Fog 1.5.7 Upgrade
- 
 Was running fog 1.5.6 and i was unable to access the gui, kept getting an error the database couldn’t connect. If i had to guess Ubuntu did an update and broke the connection. I downloaded latest version of fog and ran the installer , however it kept failing on installing the mariadb server and client. So i installed Mariadb 10.3 manually, re ran the setup of maria db server and setup a password. Re ran the fog 1.5.7 installer and still getting the error the db is not accessible. I then went into var/www/fog /lib/configclass.php and entered the new password. Now the issue is fixed on seeing the gui, however now all my data is missing , users, hosts, images. What do i do to fix this ? Thanks for the help. Ray

 This is a known problem on Ubuntu (the database moving when changing to mariadb) You will likely find your fog database in /var/lib/mysql-5.7Currently, FOG does not try to move to mariadb on Ubuntu for this reason. If possible, going back to mysql would be the best option I reckon.

 @Quazz How do i do this ?

 @Ray-Zuchowski I think uninstall mariadb and install mysql should work fine, I’m not 100% sure, but that’s where I’d start. But check the mentioned folder and see if you can find the fog database first.

 The folder is there.

 @Ray-Zuchowski Give this a try: sudo -i mv /var/lib/mysql /var/lib/mysql-mariadb apt-get remove mariadb-client mariadb-server cp -a /var/lib/mysql-5.7 /var/lib/mysql apt-get install mysql-client mysql-server systemctl start mysql
