Tim I have seen this before, where Eth0 has a priority over wireless connection, and you have to disable the wired connection for Wireless to connect. The caveat to this is that it was always on NT4 or XP boxes, never with linux.

[Dorset] Cannot Run Sonic Pi as an Ordinary User
Hi, So I built the Sonic Pi code and it is installed and launched by running the following script in /usr/src/sonic-pi-master/app/gui/qt/. rp-app-bin: #!/bin/bash #-- # This file is part of Sonic Pi: http://sonic-pi.net # Full project source: https://github.com/samaaron/sonic-pi # License: https://github.com/samaaron/sonic-pi/blob/master/LICENSE.md # # Copyright 2013, 2014, 2015 by Sam Aaron (http://sam.aaron.name). # All rights reserved. # # Permission is granted for use, copying, modification, and # distribution of modified versions of this work as long as this # notice is included. #++ eval $(dbus-launch --auto-syntax) DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" $DIR/sonic-pi If I launch it with sudo ./rp-app-bin it launches Sonic Pi and I get the ability to enter notes etc. (It doesn't work yet, but I think that is to do with jack.

Hi Terry, I'd also have thought that you would not want to be doing this with sudo - just say 'git clone ...' from your regular account. best of luck victor On 7 September 2015 at 17:29, Tim Waugh wrote: > On Mon, 2015-09-07 at 14:25 +0100, Terry Coles wrote: > > A visit to the web page at https://github.com/samaaron/sonic-pi/ > > implies that I need to sign up to access the code, so how do I do > > that from the command line? > > No, you don't need to sign up. > > On the right-hand side of that page, should see "You can clone with > HTTPS, SSH, or Subversion" below a box with a URI in it.

No, you don't need to sign up. On the right-hand side of that page, should see "You can clone with HTTPS, SSH, or Subversion" below a box with a URI in it. It should already be labelled "HTTPS clone URL", in which case that's the one you want. If not, click on the 'HTTPS' link below the box, and it will show you the right one. When you click in that box it will highlight the entire URL ready for you to copy and paste.

[Dorset] Using GitHub
Hi, I'm trying to install Sonic Pi on my Kubuntu box (it's installed by default on the Pi, but I thought it would be useful to have it running on my main machine). There are binary packages for Windows, Mac and the Pi, but nothing for x86 / amd64 based Linux machines, so I thought I'd download the source and build it from scratch. Unfortunately, I've stumbled at the first hurdle; getting the code from GitHub. A quick google threw up https://www.miskatonic.org/2015/01/17/setting-up-sonic-pi-on-ubuntu/[1] . About two screenfulls down it says, (amongst other things) to run: git clone g...@github.com:samaaron/sonic-pi.git This gives me: terry@Optiplex:/usr/local/src$ sudo git clone g...@github.com:samaaron/sonic- pi.git Cloning into 'sonic-pi'... The authenticity of host 'github.com (192.30.252.129)' can't be established. RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'github.com,192.30.252.129' (RSA) to the list of known hosts. Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. A visit to the web page at https://github.com/samaaron/sonic-pi/[2] implies that I need to sign up to access the code, so how do I do that from the command line? (I appreciate that once I'm signed up I can do what I want on the web page, but I'd like to know how to do it through the console.) (I have also spotted that I can download the whole thing as a zip file and this is currently ongoing, but I'd still like to know how to do it the console way.) -- Terry Coles [1] https://www.miskatonic.org/2015/01/17/setting-up-sonic-pi-on-ubuntu/ [2] https://github.com/samaaron/sonic-pi/ -- Next meeting: Bournemouth, Tuesday, 2015-10-06 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
