hello,  
I am using the e-series robot and the robot software version is 5.9.5.1031259. However, while using the ur-rtde c++ source, the receive interface works but the control interface does not. In the previously used CB-series robot, the source code was working normally, but I changed the robot and it did not work, so I am posting this post.

Hi, you can maybe try `sudo apt upgrade` also. It looks like the packages in ppa:sdurobotics/ur-rtde is not visible for your system. That’s why you cannot locate the necessary packages.
