Intermittent error on Linux: 'Launching updater executable'

I'm running a piece of code using the following cli commands

matlab -nodisplay -r "scriptname('input1', 'input2'); quit"

And every so often, when I sun this, it gets stuck on a terminal prompt which states

'Launching updater executable'

Hi matlabgod,

I understand you are getiing 'Launcher updater excutable' error on running a batch script. I am assuming your scriptname is a function which accepts two arguments.

Please try these following workaround/troubleshooting steps:

1 - Use -nojvm flag and -nodesktop flag in the command:

Replace your command with:

matlab -nodisplay -nojvm -nodesktop -r "scriptname('input1', 'input2'); quit"

2 - Restart MathWorks service host using command

killall -9 MathWorksServiceHost

You can also uninstall and install the MathWorks service host by following the thread here: https://www.mathworks.com/matlabcentral/answers/1815365-how-do-i-uninstall-and-reinstall-the-mathworks-service-host

3 - Try to reboot your system.

Hope this helps.

Please try using:

matlab -batch "scriptname('input1', 'input2')"

to launch MATLAB instead. More details on the -batch argument can be found here.
