I am just starting with Ubuntu, so I would like to have your help. I am trying to install a software on my notebook with Ubuntu 16.04 LTS. I did the following procedure:

  1. Open a terminal from the folder where I have the software.(Documents)

  2. Then in the terminal I typed:

    cd
sudo chown -R user:user /opt/
sudo chown -R user:user /tmp/

  3. Then I go to the folder documents by typing in the same terminal 

    cd Documents/

    then I enter ./INSTALL.

And I have an error saying permission denied.

What am I doing wrong?

  • You're doing several things wrong. Better to edit and post exactly what are you trying to install and what instructions are you trying to follow.

  • Where were these instructions from?

  • Which software are you trying to install specifically? Why did you change the ownership on /opt and /tmp? That doesn't sound like a good idea and probably doesn't achieve what you intend. What's the output of ls -l ~/Documents/INSTALL?

  • I've done a google search for "sudo chown -R user:user /opt/ and "sudo chown -R user:user /tmp/", and can't find anything

The problem is that you don't have execute permissions on the ./INSTALL file.

Fix:

cd Documents
chmod +x INSTALL

Now when you run ./INSTALL you should have permission to run it.
