Error while loading shared libraries: libIlmImf-2_3.so.24 on Ubuntu

The latest version 1.18.2 may give this error when running on Ubuntu LTS 20.04.3.

There is a missing library dependency in the package.

so below should fix this error:

apt-get install libopenexr24:amd64

robomotion@onegig:~$ robomotion-deskbot --version
robomotion-deskbot: error while loading shared libraries: libIlmImf-2_3.so.24: cannot open shared object file: No such file or directory
robomotion@onegig:~$ logout

Hi, I’m using Ubuntu 18.04 LTS 64bit on a VPS and that version doesn’t seem to exist in the repo yet, so I tried the “just install anything that starts with libopenexr*” approach.

After installing so much it looked like it took its dependencies lesson from Windows installers, it didn’t change the error that still appears: “error while loading shared libraries: libIlmImf-2_3.so.24: cannot open shared object file: No such file or directory” (and “error while loading shared libraries: libHalf.so.24” too)

Hello,

Currently only Ubuntu 20.04 is supported.

We are working on an .AppImage version of the robot that will run on any distribution.

You can follow the progress from our Roadmap Board https://feedback.robomotion.io/roadmap/appimage-for-linux

or if possible you can setup a Ubuntu 20.04 box and try to install the robot there. Here is how to setup on Ubuntu VPS

Hi,
i get the same error with Ubuntu 22.04. Guess I have also to wait for the appImage?

Yes, it is a work in progress currently.

@Rohat is working on this.
