Sudo Apt-get upgrade fails

I get a permission denied error when it comes to erasing files from the ~/oldconffiles/.config and .themes directories. I am running the command as sudo during the upgrade. Any ideas?

Thanks in advance.

Re: Pi 2 SD Card on Pi 3?

Thanks for the reply, but I don't think that is the issue because the power supply that I am using the capable of that.

Re: Pi 2 SD Card on Pi 3?

I have been running Jessie in my pi2 and just bought a pi3 and I would like to use the same sdcard. I did the all the apt-get update/upgrade/dist-upgrade to get everything current and was hoping to simply plug in the sdcard into the pi 3. Alas, when I boot the pi 3 with the old sdcard I get the gian...

Re: NMEA data to RPi2 via USB port

Good info, Karika. As it happens, my NAIS 300 also has rs485 output with bare wire terminals, so I have two further questions. 1. Can you give me an example of an adapter with a "normal Rs232 chip" that I could put into the usb port of the RPi? 2. How could I use the rs485 output to connect to the u...

Re: NMEA data to RPi2 via USB port

Thanks Geemac (et al). You are correct in that the adaptor does not work. The reason, I believe, is that NMEA data works with 5v logic and the USB-to-TTL console adapter uses 3.3v logic. I happened to have both of the items you suggested - usb to RS232 adapter and the female cable adapter - and the ...

Re: NMEA data to RPi2 via USB port

Well, I got the usb adaptor which has four colored wires. My AIS unit has three RS232 connections: -ve, gnd, +ve. I have looked at a pin out chart for the usb: red wire = +5v, white wire = data -, green wire = data +, fourth wire (black) not used. The AIS manual does not say how to make the connecti...

Re: NMEA data to RPi2 via USB port

In order to avoid frying either your RPi or your NMEA receiver OR BOTH . Spend £3 and get a simple USB to RS232 converter. http://www.ebay.co.uk/itm/like/321110901546 Thanks for the quick responses, guys. Okay... Got it no direct connect. But I need bare wires at the other end of the usb cable, so ...

NMEA data to RPi2 via USB port

Hello, I would like to connect my Navico 300 NAIS transceiver to my pi2 in order to display AIS data in Opencpn. The outputs from the NAIS transceiver are bare wire Rs232, with three connections: gnd, in, and out, power at 5v, 38400 baud. In order to make this connection, could I simply cut off the ...

How do I install Rhythymbox on my PI2

I have searched high and low to find the instructions, but have not succeeded. Can anybody tell me?

I heard that Rhythymbox allows syncing playlists with my portable mp3 player, which Clementine does not, so I would like to check it out.

Thanks in advance.
