[Koha] Koha upgrade 3.18.11 --> 3.20.07

[Bortel, Gary]

I am seeing two MySQL errors thrown when trying to update from 3.18.11 --> 3.20.07. Are these benign or something about which concern should be raised?

The installation here is Ubuntu 14.04.3 with a multi-tenant package install of Koha. Mysql  Ver 14.14 Distrib 5.5.46, for debian-linux-gnu (x86_64) using readline 6.3
