Re: GLIBC_PRIVATE not defined in file libc.so.6

Thanks for responding, I can't update the program. I went back to Jessie and it is running fine again, so I guess I will stay with that for a while. I will report it to the project.

How are you converting to VGA? From the FAQ: Note: There is no VGA output available, so older VGA monitors will require an expensive adaptor. Using an HDMI to DVI-D (digital) adaptor plus a DVI to VGA adaptor will not work. HDMI does not supply the DVI-A (analogue) needed to convert to VGA - convert...

If you only cut the red wire then this should not stop your hub working unless the mains power supply to the hub is not supplying power.

Re: Is this a SD-Card issue?

a) you cut the wrong wire b) cutting the right wire won't help anyway c) some related problems can be caused by an under powered power supply or cord but not all. c) it's a driver problem that is being worked on.
