Check Execution Permissions: Ensure that the 'install' file has execution permissions. You can set the necessary permissions using the chmod command:
chmod +x ./install
Then attempt to run the installation script again with sudo:
sudo ./install
Run with Full Path: Try executing the script with its full path. Navigate to the directory where the install file is located, and then run it:
cd /path/to/matlab_runtime/installation_folder
sudo ./install
Ensure the File System is Not Mounted with 'noexec': Sometimes, the file system might be mounted with the noexec option, which prevents execution of binaries on that mount. Verify the mount options with mount or cat /etc/fstab, and remount without noexec if necessary.
Check for File System Corruption or Read-Only Mode: If the file system has been mounted in read-only mode due to errors, you might need to check for file system corruption. Use fsck to check the file system:
sudo fsck /dev/sdX # Replace /dev/sdX with your actual device, like /dev/sda1
Be careful with this command as it can lead to data loss if used improperly.
Extract with Appropriate Permissions: Sometimes unzipping as root can set owner-only permissions. Ensure you unzip the file with the correct user permissions or change ownership with chown:
sudo chown -R $USER:$USER /path/to/matlab_runtime/installation_folder
Disable Security Features Temporarily: Security features like SELinux or AppArmor might interfere with the installation. You can temporarily disable these features to see if they are causing the issue. For SELinux:
sudo setenforce 0
Make sure to re-enable it with sudo setenforce 1 after the installation.
Consult the Installation Logs: Check if there are any logs generated by the installation script that might give you more details on why the permission is denied.
File Corruption: The downloaded file might be corrupted. Try re-downloading the MATLAB Runtime installer from the official source.
Support Forums and Documentation: If none of the above steps work, consult the MATLAB support forums or the official installation documentation for MATLAB Runtime.
Contact Technical Support: As a last resort, if you are still facing issues, you should contact MathWorks Technical Support for assistance with your installation problem.
