Dkpg errors upgrading sympl-core to 10.20220426.0

Problem Description

Wanting to upgrade to Sympl 11, I’m getting the following errors I’m having trouble resolving…
iomart support are sadly useless and keep posting links to this forum for barely related issues… I miss bytemark’s informed support!

Was this VM migrated to (or installed on) the iomart virtual server platform, or it it still running on Bytemark BigV?

It seems like the banner service which runs on boot and outputs information to the serial console might be failing, so if there’s no serial (like in the case with the container-style iomart VMs) it may simply fail, although I may be able to push a fix or work-around for it.

Hi - sorry for the later reply… but yes this I’m pretty sure this VM was migrated to the iomart system.
I set it up before Bytemark seemed to morph into iomart…
