2015-11-11 19:22:36 -0600 answered a question Install problem with ros2

Actually I fixed this myself. You go to the MIT PGP Key Server ( http://pgp.mit.edu/ ) - input the text string into the search and do the search. You will probably have to put 0x in front of your string. You then copy the key and paste it into a text file, which you can import on the command line via gpg --import key.txt

I did have a problem farther downstream however. When I tried to run the talker and listener it could not find a library. The error msg was:

error while loading shared libraries: libddskernel.so: cannot open shared object file: No such file or directory

I assume I need to get DDS now, so any advice on that?

When I attempt to install the prerequisites (OSRF sources for DDS) on the ros2 install I find a key problem. For example, when I type:

sudo apt-key adv --keyserver ha.pool.sks-keyservers.net --recv-keys D2486D2DD83DB69272AFE98867170598AF249743

it times out with the msg:

gpg: requesting key AF249743 from hkp server ha.pool.sks-keyservers.net gpg: keyserver timed out gpg: keyserver receive failed: keyserver error

Reading the net some have said to add port 80 to the command, but when I use:

sudo apt-key adv --keyserver ha.pool.sks-keyservers.net:80 --recv-keys D2486D2DD83DB69272AFE98867170598AF249743

it does not recognize that host and gives me: gpgkeys: no keyserver host provided gpg: keyserver internal error gpg: keyserver receive failed: keyserver error

I had no problem installing the original ros. Any advice appreciated.

Mr. Dornhege,

Thank you for identifying where I can download ROS 2.0

However when I try to do so, I get the following error, which my IT department says is a problem with the site. Any advice would be appreciated. The error is displayed below.

when I try:

sudo apt-key adv --keyserver ha.pool.sks-keyservers.net --recv-keys 421C365BD9FF1F717815A3895523BAEEB01FA116

I get a key error in response:

2015-11-10 11:52:19 -0600 asked a question Does ros 2.0 yet exist? If so where can I find it

I have read some descriptions about a potential ROS 2.0.

Does it yet exist?

If so where can I find it?

Thanks
