after running 'rosdep update', it shows:

reading in sources list data from /etc/ros/rosdep/sources.list.d
Hit http://github.com/ros/rosdistro/raw/master/rosdep/osx-homebrew.yaml

ERROR: unable to process source [http://github.com/ros/rosdistro/raw/master/rosdep/base.yaml]:

<urlopen error _ssl.c:489: The handshake operation timed out> (http://github.com/ros/rosdistro/raw/master/rosdep/base.yaml)

ERROR: error loading sources list:

this is my first time to install ROS, and I don't know how to deal with this error.. What I have to do now? Thank you!

Hello demmeln~

after I run python -c 'from urllib2 import urlopen; print(urlopen("http://github.com/ros/rosdistro/raw/master/rosdep/base.yaml", timeout=5).info());'

if you have the same problem .maybe you can try to repeat the command 'rosdep update'.. I don't know what happened but sometimes it really works ..

Can you please edit your answert to print the output of excuting in your terminal:

cat /etc/ros/rosdep/sources.list.d

From the error message it seems like there is a missing second slash after http:/, but that might just be formatting.

Are you able to view http://github.com/ros/rosdistro/raw/master/rosdep/osx-homebrew.yaml in your browser and download it in the terminal with wget http://github.com/ros/rosdistro/raw/master/rosdep/osx-homebrew.yaml?

Also, are you using ubuntu? Which version? How have you installed rosdep (apt or pip?) and is your installation up to date?

Edit:

Have you executed the rosdep update command repeatedly? Does it always fail the same way?

What does rosdep --version output?

Edit2:

You can directly check the following, if it is a problem that is not really related to rosdep, but rather either github, your local setup or python:

python -c 'from urllib2 import urlopen; print(urlopen("http://github.com/ros/rosdistro/raw/master/rosdep/base.yaml", timeout=5).info());'

Edit3:

So this really comes down to your machine / your python urllib2 not timeing out on that address, which seems not to be a problem with rosdep as such. You could try one thing, and replace the contents of file /etc/ros/rosdep/sources.list.d/20-default.list with and see if that makes a difference for the rosdep update call. Update: Don't do that, it doesn't seem help and if you forget to undo it, you are left with stale sources.

Edit 4:

Ok, I'm out of ideas, it seems to be that some urls you can access, and some URLs you can't. Maybe it is a github problem, maybe it is a problem of your computer. You could try with a different machine or a virtual machine from the same network to narrow it down further. Or try with your machine from a different network. It's probably best to remove the file you just changed /etc/ros/rosdep/sources.list.d/20-default.list and call sudo rosdep init again.

Edit 5:

The problem seems to persist for multiple people and changing URLs. Some people report success after trying multiple times and/or across multiple days.

I'm not sure what is going on. It is strange that you are able to access the file with wget but not rosdep...

this problem really makes me crazy.. could you please executed the rosdep update command and post the result? thank you a lot!

You can always continue the installation without rosdep, for example by editing the file `/etc/ros/rosdep/sources.list.d/20-default.list` to comment out any files you can access at the moment. After that, the update should complete. You have to be aware that rosdep will not be fully functional, but

it should be possible to get started with ROS even without rosdep. If you install the packages from apt, you don't need rosdep anyway. You only need it if you build additional packages from source, end even then, there are ways to work around it.
