I have the above problem after recently installing matlab. The error messages coming up are:
Gtk-Message: 21:25:02.923: Failed to load module "pk-gtk-module"
Gtk-Message: 21:25:02.923: Failed to load module "canberra-gtk-module"
When I try to install package gtk3-devel-3.22.2 using sudo dnf install gtk3-devel-3.22.2 the following error message comes up
/usr/bin/sudo must be owned by uid 0 and have the setuid bit set,
so all my permissions have been messed up by the install. I now probably need to re-install linux.
How many times can I re-install and validate on this machine? I wish to execute Matlab programs on this, and another machine as a home project. Could you please advise me as to ehere I should go from here? Can I install an earlier version of Matlab if necessary?

I Understand that you're experiencing issues with GTK modules following your MATLAB installation on Linux. These warning messages about missing GTK modules.
Here's a solution to address the permissions and GTK warnings without needing to reinstall your Linux system:
1. Create a Startup Script:
  • Open your terminal.
  • Navigate to a directory where you'd like to place the startup script.
  • Use the `touch` command to create a new script file:
touch matlab_start.sh
2. Edit the Startup Script:
  • Open `matlab_start.sh` in your preferred text editor.
  • Insert the following content into the script:
#!/bin/bash
export GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0
/path/to/matlab/bin/matlab
Make sure to replace `/path/to/matlab` with the actual path to your MATLAB installation.
3. Make the Script Executable
a. Back in the terminal, grant execution permissions to the script:
chmod +x matlab_start.sh
For additional information, refer the following MathWorks documentation:
