the state_publisher executable is deprecated
Hi there, I'm new to ROS and on Melodic. I was going through the URDF tutorials where I'm facing the following errors -
1.[ WARN] [1586385079.319484096]: The 'state_publisher' executable is deprecated. Please use 'robot_state_publisher' instead
2 The Controller GUI isn't showing up
3.TIFFReadDirectory: Warning, Sum of Photometric type-related color channels and ExtraSamples doesn't match SamplesPerPixel. Defining non-color channels as ExtraSamples..
4.TIFFFieldWithTag: Internal error, unknown tag 0x829a.
Please tell me where I've gone wrong and how to fix them..
