./install in terminal gives error "sudo: ./install: command not found"

I want to install Matlab in Ubuntu. I downloaded the latest version of matlab software, unziped, In the terminal chaged the current directory to the file where i extracted the matlab installation file. I tried the command " sudo ./install" it gives following error "sudo: ./install: command not found" I also observed, there is no file name install in the installation folder

I thought it was install.sh ?

[Pavana Mysore Ganesh]

I got command not found, even after using install.sh

[Walter Roberson]

What file names do you observe?

[Pavana Mysore Ganesh]

I corrected the mistake, I was downloading windows installation file. Thanks

[abed hyasat]

how did you solve it?

[Walter Roberson]

If ./install exists in your current directory, and you are using Linux, but sudo ./install says that the command is not found, then you might be accessing a filesystem that has the no-execute flag set. In that case you can try

sudo sh ./install

it still says permission denied,

[Alex]

./install: 1: exec: /root/matlab_R2024b_Linux/bin/linux-arm-64/install_unix_legacy: not found

root@395e5367ea7a:~/matlab_R2024b_Linux# cd bin

root@395e5367ea7a:~/matlab_R2024b_Linux/bin# cd glnxa64/

install_unix_legacy is not supported, looks like they want you to figure this out your self, anything without GUI is no longer supported, they have moved all these legacy files away.

it says 'sh: 0: Can't open ./install'

[Walter Roberson]

Does install exist in the current directory? What permissions does it have?

[Riadus Salehin]

No, there is not any install directory

Please, has anyone been able to solve this problem?

In my case, I got "sudo: ./install: command not found" when running "sudo ./install". Then, I tried " sudo sh ./install" as recommended above, but it still did not work "./install: 1: exec: /home/gaofei/Matlab_setup/setup/matlab2020a/bin/glnxa64/install_unix: Permission denied".

I am trying to install Matlab 2020a on a Linux server

Please, any suggestions would be highly appreciated.

@Patrice Monkam is that file system mounted with the noexec flag?

For example is a USB thumb drive mounted there, or a disk image? USB thumb drives tend to automatically mount with noexec .

[Patrice Gaofei]

@Walter Roberson Sorry, I am not sure whether I understood you very well. Actually, the downloaded file is in iso format (that could be seen as CD). I simply unzipped the content to my current directory. I had installed it before, but on windows operating system.

I have tried various tricks based on online contents, but all in vain. I have been stuck here for almost a day now.

[Patrice Gaofei]

This is what I am getting now as error.

terminate called after throwing an instance of 'std::runtime_error'

what(): Unable to launch the MATLABWindow application

Aborted

after running

sudo sh ./install

[Walter Roberson]

I recommend contacting Mathworks for free installation assistance.

[Patrice Gaofei]

@Walter Roberson Thank you very much for your time and suggestions! I have submitted a request, still waiting for their reply.

In the meantime, anything to try while waiting?

[Walter Roberson]

Could still be -noexec problem or needs

 sudo chmod -r ugo+x .

The final period is part of the command

Dear Mr. @Walter Roberson, I am very grateful for your time and help. It seems like the problem was from the way I extracted the installation files from the MATLAB ISO file downloaded online. I had to mount the iso file following the steps in this link.

Then, I activated the installed Matlab following this link

https://www.mathworks.com/matlabcentral/answers/99457-how-do-i-activate-matlab-or-other-mathworks-products

It took me almost three days. I will now proceed with installing other tools and packages.

I am sharing this in case it might help others.

Regards,
