Since the upgrade to Ubuntu 14.04 (Trusty Tahr) I have had issues running the Android SDK Tools. For example this error:
bash: ./adb: No such file or directory
Check the multi-arch architectures installed on the system.
sudo dpkg --print-architecture
Mine only showed ‘amd64’. Turns out you need to add the i386 architecture and install libc6:i386,libncurses5:i386,libstdc++6:i386 library packages.
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
