GuiRunner error: failed to get plugin

[ggiulian]

Whenever I run any gazebo command which is for example ign gazebo empty.sdf or ign gazebo shapes.sdf this error appears. For now, it is not giving too many problems because the simulation is not affected. But for future applications I don't know if it will be an inconvenience

Environment

• OS Version: Ubuntu 20.04
• Source or binary build?
  source, Ignition Edifice and Galactic
• If this is a GUI or sensor rendering bug, describe your GPU and rendering system. Otherwise delete this section.
  • Rendering plugin: [ogre | ogre2].
    • Sensor rendering error.
    • GUI rendering error.
  • EGL headless mode:
    • Running in EGL headless mode
  • Generally, mention all circumstances that might affect rendering capabilities:
    • running on a dual GPU machine (integrated GPU + discrete GPU)
    • running on a multi-GPU machine (it has multiple discrete GPUs)
    • running on real hardware
    • running in virtual machine
    • running in Docker/Singularity
    • running remotely (e.g. via SSH)
    • running in a cloud
    • using VirtualGL, XVFB, Xdummy, XVNC or other indirect rendering utilities
    • GPU is concurrently used for other tasks
      • desktop acceleration
      • video decoding (i.e. a playing Youtube video)
      • video encoding
      • CUDA/ROCm computations (Tensorflow, Torch, Caffe running)
      • multiple simulators running at the same time
    • other...

Description

• Expected behavior: No Gui error
• Actual behavior: Gui error, failed to get plugin

Output

That error should be harmless and will disappear once we release gazebosim/gz-sim#944 for Fortress. I'll keep this issue open until we do so.

Ignition Gazebo 6.2 has been released for Fortress and 5.3 for Edifice
