Cannot connect to serial [Linux]

Hi, I cannot open any serial port to comunicate with my Arduino Micro.

instrhwinfo('serial')

ans = 

    HardwareInfo with properties:

       AvailableSerialPorts: {0×1 cell}
             JarFileVersion: 'Version 3.11'
      ObjectConstructorName: {0×1 cell}
                SerialPorts: {0×1 cell}

Access to your hardware may be provided by a support package. Go to the Support Package Installer to learn more.

I already tried using the java.opts file

-Dgnu.io.rxtx.SerialPorts=/dev/ttyS0:/dev/ttyS1:/dev/USB0:/dev/ttyACM0

I'm both in the uucp, dialout and lock group. Permissions on serial ports are

crw-rw---- 1 root  uucp 166,  0 Jul 27 18:42 /dev/ttyACM0
crw-rw-rw- 1 root  uucp   4, 64 Jul 27 14:26 /dev/ttyS0
crw-rw-rw- 1 root  uucp   4, 65 Jul 27 14:26 /dev/ttyS1
crw-rw-rw- 1 root  uucp   4, 66 Jul 27 14:26 /dev/ttyS2
crw-rw-rw- 1 root  uucp   4, 67 Jul 27 14:26 /dev/ttyS3
crw-rw-rw- 1 root  uucp 188,  0 Jul 27 18:40 /dev/ttyUSB0

Arduino is already plugged when MATLAB starts. If I click on the Support Package Installer link it does nothing. If I try to type the

supportPackageInstaller

command, it does nothing. I tried using all other answer provided here, but no one is working.

Am I missing something? Is there a way to fix this?

Of course, I can read data if I use

cat /dev/ttyUSB0

or using the Arduino IDE or Processing.

It looks like you are not able to launch Add-Ons Manager that is used to install and setup Support Packages. MATLAB needs the support package to be able to communicate with Arduino. I have included below the corresponding links so that you could try to manually download it.

Arduino Support from MATLAB: https://www.mathworks.com/hardware-support/arduino-matlab.html

Arduino Support from Simulink: https://www.mathworks.com/hardware-support/arduino-simulink.html

Another point I want to mention is that MATLAB/Simulink is qualified with a limited number of Linux distributions, and unfortunately, Arch Linux is not one of them. So you may encounter some unexpected issues like these with MATLAB on Arch Linux.
