Du har nog bara "fastnat" precis i övergången. De verkar ha en del strul just nu.

Since one of the components being upgraded will be the networking system itself, the upgrade is likely to fail halfway through because it cannot download things while the network was being reset (a problem in the package manager that may have been fixed now). Don't worry, just wait for the reboot and re-run the upgrade. You might even need to repeat this.

I guess at this point, it'd be faster to just re-flash the box, than to run the online upgrade. But hey, that's for you to decide.
OpenPLi - Really BIG upgrade tomorrow
