b2g(FirefoxOS) configure.sh repo sync でエラー

curl: (22) The requested URL returned error: 404
Server does not provide clone.bundle; ignoring.

サーバーの調子が悪いのかな？

so you need to edit .repo/manifest.xml and change this line

<remote name="linaro" fetch="git://android.git.linaro.org/"/>

for this

<remote name="linaro" fetch="">http://android.git.linaro.org/git-ro/"/>
