Your bundle does not meet the requirements.
I've downloaded it, and sugar-install-bundle says what is wrong;
sugar3.bundle.bundle.MalformedBundleException: All files in the bundle
must be inside a single directory whose name ends with '.activity'
Sure enough, "unzip -l" shows the directory name
Clicking on http://download.unleashkids.org/HaitiOS/bundles/livreshaiti.xol
works in Sugar's Browse activity on OLPC OS 13.2.9, correctly loading books
into Sugar.
However doing the same thing from the command-line ("sugar-install-bundle
livreshaiti.xol") does not work :/
Does anyone have any
