@toschulz So I suspect the problem is due to a divergence of db schema between dev-branch/stable + working-1.6

If you can update yoru Mysql directly:

sudo mariadb -u root fog (if no root password of course - if you have a root password add -p

UPDATE schemaVersion SET vVersion=0;

Then refresh your screen, click the install/update, and hopefully the error will go away.

The way the schema is configured is it will attempt (idempotently) to rerun every single SQL query in the schema chain.

This should fix the problem you’re seeing.

I believe there’s a column on the login history piece being requested that may just simply be missing which would cause the issue with datatables.
