0. Open the X Terminal

1. Make shure that python-gdata is installed:
$python
>>>import gdata
There shouldn't be any error message.

2.Make shure that /opt/ytcli/ytcli.py + /opt/ytcli/ytcli_queue.py are installed.

3.Go root and edit /usr/bin/ytcli: replace "bash" with "sh" at line #1

4. Check if ytcli is user executable or use chmod to set it.

If any of those steps do not work you should wait until shapeshifter will hopefully provide a new fixed package.
