Public bug reported: I'm pretty green, so I really couldn't say what the problem is -once the new software channels have been set, I keep getting the following error message:
Could not determine the upgrade An unresolvable problem occurred while calculating the upgrade. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. -> Points 1 and 2 are not the case -I'm with U 13.10, trying to upgrade using the Update Manager. -> Point 3 is a possibility, but how can I find out? More data: -> CPU: AMD FX(tm)-6100 Six-Core Processor × 6 -> Graphics: GeForce 210/PCIe/SSE2 -> OS-Type: 64bit Can anybody help me?
