I just tried to upgrade from 5 to 6 on my microserver and it all went horribly wrong.

 

I have a backup of the USB stick so that's a good start, but here's what's happened so far.

 

I ran the plugin to upgrade and rebooted, then it didn't come back. I then hooked up a monitor and found incompatible syslinux files were causing it to not boot. In the end I formatted the USB stick, copied the v6 files over and ran make_bootable. I then copied over my old config folder, replacing files and rebooted.

 

Now it boots fine, I can SSH to it ok but there is no UI, just a blank screen.

 

Here is the tail of my syslog:

Running out of ideas here, any help would be appreciated.

 

OK, think I solved it, it was my plugins directory.... blatted that and rebooted and now the UI is up!
