pin that's hopefully the solution! will attempt a fresh install again tonight!
EDIT: Yep, that fixed it.
FYI, I also fixed the error message I was getting with DHCPv6, just added
Finally up and running (again) with the most current 9-stable img. Here's hoping I don't bork this one!
On a positive note, the experience has been helpful in learning a bit more about the system. I've even written myself a personalised installation guide addressing all of the difficulties I encountered, should I ever need to reinstall again.
Cheers again @pin for your help, that beer is still on offer should you decide to take it up 👍️
