How to downgrade ROS Noetic or Gazebo to an earlier version?
Hi, recently apt updated ros-noetic-desktop-full, and my ROS package no longer works correctly. I suspect this is due to Gazebo being updated. After the update, the surface of my cylinder mesh in my Gazebo world no longer displays correctly.
I have a cylinder model in collada (.dae) format, that has a gradient texture on the inside face, in the old version the gradient was flat and clearly visible, but now the gradient is not plain to see, it almost looks as though the surface is reflective. I'm not allowed to post photos, so I have uploaded some to google photos instead. The cylinder is supposed to look like this: https://photos.app.goo.gl/VVs3VkVvvvY... But now looks like this: https://photos.app.goo.gl/fWX5pEUHX5j...
The only light source illuminating the cylinder is a point light in the centre. I noticed in the Gazebo changelog that point lights have been updated to cast shadows not, but I have shadows turned off for the point light in the world file.
So my question is then, how do I revert to the previous version of ros-noetic-desktop-full, with all of its included packages (e.g. Gazebo), or if this is not possible then how can I downgrade just my Gazebo version. Otherwise if anyone knows how to fix the issue with the newer Gazebo version I'd be very grateful to know. My Gazebo version was updated from 11.9.0-1~focal to 11.10.2-1~focal. ros-noetic-desktop-full updated from 1.5.0-1focal.20220413.180024 to 1.5.0-1focal.20220422.194323. I am on Ubuntu 20.04.4 LTS.
