While loading gazebo I’m getting the following error

gzserver: error while loading shared libraries: libdart-collision-bullet.so.6.12: cannot open shared object file: No such file or directory

however when I try to install libdart-collision-bullet-dev, it says  
libdart-collision-bullet-dev is already the newest version (6.9.2-2build4).

Can anyone help me out with what’s wrong?

just passing by

it seems that the gazebo you have installed has been built with a newer libdart-collision-bullet

I would recommend trying to reinstall gazebo and see if the error still shows up and doesn’t self - resolve

Thank you for the reply!

I tried reinstalling gazebo using the gazebo documentation

> **[Gazebo : Tutorial : From source (Ubuntu and Mac)](https://classic.gazebosim.org/tutorials?tut=install_from_source)**
>
> The Gazebo robot simulation

In the ### Build And Install Gazebo step  
I ran the following command in /tmp/gazebo/build

```auto
cmake ../

```

it gave me the following error:

```auto
Could not find a package configuration file provided by "sdformat9"
  (requested version 9.8) with any of the following names:

    sdformat9Config.cmake
    sdformat9-config.cmake

```

I installed dependencies using the following link

> **[Gazebo : Tutorial : Dependencies from source](https://classic.gazebosim.org/tutorials?tut=install_dependencies_from_source)**
>
> The Gazebo robot simulation

but still end up with the same issue

Is there any other dependency I might be missing?

What linux distribution are you using?

You should try to avoid building from source if possible.

So for ubuntu 20, the version of gazebo to use is gazebo 9.

What is the output of sudo apt install gazebo9?

So I uninstalled gazebo using

```auto
sudo apt-get remove '.*gazebo.*' '.*sdformat.*' '.*ignition-math.*' '.*ignition-msgs.*' '.*ignition-transport.*'

```

installed the dependencies from the below link

> **[Gazebo : Tutorial : From source (Ubuntu and Mac)](https://classic.gazebosim.org/tutorials?tut=install_from_source)**
>
> The Gazebo robot simulation

and then tried  
`sudo apt install gazebo9`

it gives the below error :

```auto
gazebo: error while loading shared libraries: libsdformat9.so.9: cannot open shared object file: No such file or directory

```

Just a note : I have previously faced this issue and installed the library manually, which asked for more dependencies, after finally resolving those dependencies I land with my original error i.e.

```auto
libdart-collision-bullet-dev is already the newest version (6.9.2-2build4).

```

Hello @Yashas_Shetty, could you resolve this issue?

No actually. I ended up using a docker container.  
Afterwards I also reinstalled my ubuntu and did not encounter this issue when I installed ros1 and gazebo.
