The hwmatch error message is back and the no server specified is still there.
Interesting that Zorin brought back the 'hwmatch' error. It may be related to the 'no server' error. I'll keep looking a bit more too. Who knows... we may find something yet.
This is not a recommendation, but should you decide to delete Zorin, I wonder if these errors would then clear. Deleting an OS can be risky to the whole system which is why I'm not recommending it. But should you attempt it, the best approach would probably be to boot into Kodachi, use Gparted to delete the Zorin partition (gotta be sure which one that is!)... and then run
sudo update-grub
to cleanly remove Zorin from the GRUB config (hopefully).
Or, rather than delete the Zorin partition, you could also just format it with Gparted so it would still be intact, as is, for future Linux installation. Don't delete any swap partitions though. Don't delete any /home partition, if you have one, as it may be shared with Kodachi. Multi-boot stuff is tricky, and not my specialty. (Heck, I don't even have a specialty!
)
If you decide to delete Zorin, be sure to backup anything critically important to you... from all 3 systems. There's nothing like a catastrophic disaster to ruin your day!
No blame to you if you don't want to go that far either. It's a lot of risk for little reward.
