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…

After a bit more digging, im fairly sure this is due to the fact the VM no longer has a serial interface, so when the ‘sympl-core’ service tries to start (which outputs the Sympl banner to the serial console then exits), it’s failing and the package is taking that as a failure.

I should be able to fix this in the package, but it’ll require a bit of tinkering - I’ll be in touch directly.

Thanks for your advice… I think the best option for now is to migrate to mythic beasts for hosting which I’m in the process of setting up now… should work out slightly cheaper and the support seems MUCH better too!
