MySQL backend, specifically:

Server version: 5.6.28-76.1-56-log Percona XtraDB Cluster (GPL), Release rel76.1, Revision f9b078d, WSREP version 25.14, wsrep_25.14

If I use a local mariadb (mariadb-server-5.5.52-1.el7.x86_64) the upgrade works fine. I’m a mysqlidiot, unfortunately, so any hints here would be greatly appreciated.

Thanks!

Hi @YoungCurmudgeon - are you trying to upgrade to v3.6.0 or v3.6.1?

I think there was an issue with upgrade on some databases, but we put a fix in v3.6.1 so can you see if that works and let us know?

That was actually 3.5.1 to 3.6.0, but yes, thank you for linking me to that issue–that looks like mine.
