سلام
میخواستم نرم افزار ros رو روی ubuntu 17.10 نصب کنم که طبق این لینک
http://wiki.ros.org/indigo/Installation/Source پیش رفتم ولی پس ازاجرای فرمان :
rosinstall_generator desktop_full --rosdistro indigo --deps --wet-only --tar > indigo-desktop-full-wet.rosinstall
خروجی زیر رو تو ترمینال مشاهده کردم
desktop-full-wet.rosinstall
Traceback (most recent call last):

raise socket.timeout(str(e) + ' (%s)' % url)
socket.timeout: timed out (http://repositories.ros.org/rosdistro_cache/indigo-cache.yaml.gz)
حالا منظور از این خروجی مخصوصا خط آخرش چی هست آیا دستور ناقص اجرا شده وراه حل رفع این مشکل چی هست؟
