We’re looking into this. There may be a bug introduced in Beta 8. The current workaround for those who experience this, is to do your upgrade with Beta 7. Complete the upgrade steps in the docs before then upgrading to beta 8 in the StartOS interface, over the air.

Or, you might just wait for beta 9 to solve the issue before upgrading from 0.3.5.1.
