I understand that you are unable to launch MATLAB on Ubuntu 22.04 after an update, possibly due to MATLAB installation issues.
Please follow the below mentioned steps to resolve these issues:
- Check Executable Path and Permissions:
a. Verify that MATLAB is correctly linked in the system's PATH by running the following command in terminal:
echo $PATH
whereis matlab
b. If MATLAB is not in the PATH, create a symbolic link to the MATLAB executable: by entering this command in the terminal
sudo ln -s /path/to/matlab/bin/matlab /usr/local/bin/matlab
c. Ensure necessary permissions to execute MATLAB by changing ownership of the MATLAB directory in terminal:
sudo chown -R username /path/to/matlab
2. Install the “matlab-support" package using below command in terminal:
sudo apt-get install matlab-support
You may need to manually terminate the MATLAB command if it hangs during installation.
3. Desktop Shortcut: If the desktop shortcut is problematic, manually create a `.desktop` file by following below steps:
a. Navigate to “/usr/share/applications”
b. Find a simple `.desktop` file to use as a template
c. Copy and edit the new file to point to the MATLAB installation path.
d. Ensure the file has executable permissions.
4. Remove the MATLAB preference directory found in the home directory under `.matlab`.
These steps should help in troubleshooting and resolving the issue with MATLAB not launching.
