Did you source git-prompt.sh (where __git_ps1 is defined)?
In Fedora I have:

source /usr/share/git-core/contrib/completion/git-prompt.sh
export PS1='[\W$(declare -F __git_ps1 &>/dev/null && __git_ps1 " 
(%s)")]\$ '
export GIT_PS1_SHOWDIRTYSTATE=true
export GIT_PS1_SHOWUNTRACKEDFILES=true

This is for Fedora, but the rationale should be the same on Ubuntu:
