Hello,
I upgraded Ubuntu 20.04 to the 22.04 version. I installed ROS2 Humble (sudo apt install ros-humble-desktop-full) and I wanted to use Gazebo Classic with Nav2 simulations, but I cannot use it - my packages have unmet dependencies, that I couldn't fix.
Please hint me what I should do now.
My terminal logs:
- When I tried normal
sudo apt install gazebo:
ljaniec@ljaniec-PC:~$ gazebo Command 'gazebo' not found, but can be installed with: sudo apt install gazebo ljaniec@ljaniec-PC:~$ sudo apt install gazebo Reading package lists... Done Building dependency tree... Done Reading state information... Done Some packages could not be installed.
