@jmeyer This is a bug in schema step 284 on MySQL. Your data did not cause it.
Cause: on MySQL, an ALTER TABLE re-checks the default of every column. Your hosts.hostSecTime still has the old default 0000-00-00 00:00:00. MySQL’s default sql_mode (NO_ZERO_DATE) refuses that default, so the step stops. MariaDB servers do not show the problem.
Fix: https://github.com/FOGProject/fogproject/pull/1838 is merged into dev-branch. While the steps run, the schema updater now relaxes the zero-date check for its own session.
The fix reaches the stable release on October 11. To continue now, install from dev-branch:
cd /root git clone -b dev-branch https://github.com/FOGProject/fogproject.git fogproject-dev cd fogproject-dev/bin ./installfog.sh -yThe failed step changed nothing in your database, so you do not need to restore the backup. The backup the installer made is still at /home/fogDBbackups/fog_sql_1.5.10.2482_20261009_113907.sql.
