./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,

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 .

@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.

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.

@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,
