adb insufficient permissions for device


You are trying to use the Android Debug Bridge (adb), but running it from the command line trying to list the connected devices you get the error:

insufficient permissions for device


You would need to start the adb server with su permissions, so you can try the following:

adb kill-server
sudo adb start-server
adb devices
adb logcat

Creating a Vagrant Box with Debian Lenny 32, rvm and Ruby 1.9.3

As an addition to the excellent beta book ‘Deploying Rails’, as I had problems using the suggested lucid64 image, I’ve tried to install a debian lenny 32 image with rvm and Ruby 1.9.3.

The steps needed are listed below


  1. Download the lenny package:
    localhost$ vagrant box add debian-lenny-32
  2. Make a new directory for the virtual box:
    localhost$ mkdir -p ~/deployingrails/lenny32
  3. change into created directory and create the Vagrant file:
    localhost$ cd ~/deployingrails/lenny32
    vagrant init
  4. change the Vagrant file to use the virtual box we have downloaded: do |config| = "lenny32"
  5. Start the VM:
    localhost$ vagrant up
  6. If there is a warning about the Guest additions here install the latest guest additions by following the description here, but only use the update and upgrade steps as:
    localhost$ vagrant ssh
    vagrant$ sudo apt-get update
    vagrant$ sudo apt-get upgrade
  7. After finishing the upgrade logout (exit) from the VM and issue the command to restart the VM:
    localhost$ vagrant reload
  8. login to the VM again:
    localhost$ vagrant ssh
  9. Install curl to be able to download the installation script for:
    vagrant$ sudo apt-get install curl
  10. Download and install rvm by using the script described here :
    vagrant$ bash -s stable < <(curl -s
  11. Add the loading of the RVM function into .bashrc, by running the following in the command prompt:
    vagrant$ echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bashrc
  12. Reload the bashrc file:
    vagrant$ source ~/.bashrc
  13. Make sure that the rvm is loaded as function:
    vagrant$ type rvm | head -1
    rvm is a function
  14. Run the rvm requirement to see the needed libraries and then run the suggested ones (except libreadline6 and libreadline6-dev that are not there in debian):
    vagrant$ sudo apt-get install build-essential openssl curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison
  15. Install Ruby 1.9.3 :
    vagrant$ rvm install ruby-1.9.3
  16. Use the ruby 1.9.3 as default:
    vagrant$ rvm use 1.9.3 --default
  17. Finally create a new VM package to use in future:
    localhost$ vagrant package --output lenny32-rvm-ruby193
  18. And add it our box list:

    localhost$ vagrant box add lenny32-rvm-ruby193 lenny32-rvm-ruby193
    localhost$ vagrant box list
