Error while installing rosjava
I am on my way to install rosjava and I followed exactly the tutorial in book ROS Projects (URL Link).
I’ve been trying to install it for many times but there are still errors coming out. From your expertise, any idea why it is not working? Thank you so much for your great support.
Here are the commands I tried:
$ sudo apt-get install ros-indigo-rosjava
$ mkdir -p ~/rosjava/src
$ cd ~/rosjava/src
$ wstool init -j4 ~/rosjava/src https://raw.githubusercontent.com/rosjava/rosjava/indigo/rosjava.rosinstall
$ source /opt/ros/indigo/setup.bash
$ cd ~/rosjava
$ rosdep update
$ rosdep install --from-paths src -i -y
$ catkin_make
And here is the error output:

I've already added it, but please include the error directly in your question next time. Without the error message, your question does not make much sense (as we don't know what "errors are still coming out').
As we're seeing SSL errors: are you behind a proxy that is doing some kind of MitM?
Hi, Thank you so much for adding the error. May I please ask how do you mean by saying behind a proxy that is doing some kind of MitM? I am so sorry that I am a beginner of ROS and Linux. Thanks a lot.
Are you in a university or a company that requires you to use a HTTP/HTTPS proxy server? If so, it may be interfering with your network traffic in a way that makes the download fail.
It's just one option though, so may not be the cause here.
