sudo rosdep init && rosdep update

报错：

lufeng@lufeng:~$ sudo rosdep init && rosdep update
Traceback (most recent call last):

    from __future__ import print_function
SyntaxError: from __future__ imports must occur at the beginning of the file

解决：

gedit /usr/lib/python2.7/dist-packages/rosdep2/sources_list.py

将

from __future__ import print_function

移到代码第一行即可解决问题

再次执行

sudo rosdep init && rosdep update

又报错：

ERROR: cannot download default sources list from:
