I followed the instruction, when I want to remove gz-garden using sudo apt remove gz-garden, there is a mistake as follow:
Reading package lists… Done
Building dependency tree
Reading state information… Done
You might want to run ‘apt --fix-broken install’ to correct these.
The following packages have unmet dependencies:
gazebo9-plugin-base : Depends: gazebo9 (= 9.19.0-2~focal) but it is not going to be installed
E: Unmet dependencies. Try ‘apt --fix-broken install’ with no packages (or specify a solution).
How could I resolve this, thanks
