Updated key server for ROS kinetic

[MixieVR]

Hi there!

First of all thanks for this repo, it has helped me a lot with my ROS projects.

This weekend the travis builds started failing for the kinetic distro with the following error:

E: There were unauthenticated packages and -y was used without --allow-unauthenticated
The command "sudo apt-get install -y python-catkin-pkg python-rosdep python-wstool ros-$ROS_DISTRO-ros-base" failed and exited with 100 during .

This was caused by the key server that apparently no longer works on line 72 of travis.yml:

- sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116

I replaced this with

sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

which is the key server used in the ros tutorials.

Now the travis build works again. Not sure if this is the correct way of resolving this problem but I thought I'd share anyway.

Hi @maximliefaard!! Currently, as you can see from my script (it is available at the link), I'm used to installing ROS Kinetic in this way:

env:
  global:
    - ROS_DISTRO=kinetic
    - ROS_CI_DESKTOP="`lsb_release -cs`"  # e.g. [precise|trusty|...]

before_install:
  - sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $ROS_CI_DESKTOP main" > /etc/apt/sources.list.d/ros-latest.list'
  - wget http://packages.ros.org/ros.key -O - | sudo apt-key add -
  - sudo rm /var/lib/dpkg/lock
  - sudo dpkg --configure -a
  - sudo apt-get update
  - sudo apt-get install ros-$ROS_DISTRO-desktop-full

Ah nice @gsilano! Does this ensure that you do not need to update the apt-key command later?

[gsilano]

Mhmm, actually I don’t know. Try using my script and let me know if you can fix the issue or not.

[MixieVR]

Yea this also fixes it! But my suggestion works too: sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

The apt-key command in this repo is still outdated but fortunately I can now continue with my own travis builds.

[gsilano]

Therefore, I think you can close the issue :smile:

Hi @maximliefaard . Thanks for the report and fix suggestion. I believe it will fix the travis build file, although another issue is preventing the example packages from successfully building. I'll keep looking at this and complete the pull request #20 . There's no need to change more than the one line you posted in the .travis file from what I can tell so far.

Okay, PR #20 fixes this (at the cost of dropping support for jade). Thanks for reporting this @maximliefaard. Please let me know if this fixes the issue for you, in the meantime I will close this.
