gzserver: error while loading shared libraries: libdart-collision-bullet.so.6: cannot open shared object file: No such file or directory

edit

I don't even know how did this happen. One day, I just open the laptop and start to work. Suddenly, it's not working anymore.

I can't even run turtlebot3. I reinstalled foxy and gazebo11. No luck. It just...out of blue not working again.

killall gzserver/killall gzclient/ pkill doesn't help at all. ANy idea? I really want to use gazebo again

error

gzserver: error while loading shared libraries: libdart-collision-bullet.so.6: cannot open shared object file: No such file or directory

even i reinstall gazebo11, this happens still.

bwuk@robots:~$ cd /usr/local/bin/gazebo
bash: cd: /usr/local/bin/gazebo: No such file or directory
bwuk@robots:~$

I still have .model though

bwuk@robots:~$ cd .gazebo/models/
bwuk@robots:~/.gazebo/models$

Everytime I load gazebo from launch, it simply frozen, crashed or says directory doesn't exist.

How did this happen?

I even echo path, but it just don't show any result

bwuk@robots:~$ echo $GAZEBO_RESOURCE_PATH

bwuk@robots:~$ echo $GAZEBO_PLUGIN_PATH

bwuk@robots:~$

I'm using foxy, gazebo11 and ubuntu 20.04
