I’m setting up a new Ubuntu installation (Quantal Quetzal) and I’m going to play with some Android code on it.

The first test I did after installing the Android SDK gave me this result:

BUILD FAILED
/home/max/AndroidSDK/android-sdk-linux/tools/ant/build.xml:377: The Android Ant-based build system requires Ant 1.8.0 or later. Current version is 1.7.1

This is not what I needed, but fortunately the solution is easy enough.
Doing something like this solved my issue:

root@praxi:~# aptitude install ant=1.8.2-4build2

Done
