I am new to Ubuntu and I am having trouble to set up a software called Topspin in my computer. I followed the instructions from this previous post how to install topspin 4.08 in ubuntu 19.10 . However, when I try the last step that involves the following piece of code:

# pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY topspin-4.1.4-linux.sh

It returns

/usr/bin/env: ‘topspin-4.1.4-linux.sh’: No such file or directory

Can anyone help me please?

  • The system tells you it cannot find the file ‘topspin-4.1.4-linux.sh’. So, either you do not have it or it is located in another directory than the current one. Could you check? – Marc Vanhoomissen May 11 '22 at 10:55
  • Hi, yes I am in the correct directory. I can try to open the file by entering: "./topspin-4.1.4-linux.sh" and fails to install. This is expected according to the previous post. That is why they add the he command "# pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY". However when I add it gives the message "/usr/bin/env: ‘topspin-4.1.4-linux.sh’: No such file or directory" – Quijanov May 12 '22 at 01:55
  • why are you using env? That doesn't do what you probably think it does. env is used to use an Environment Variable or the current system / runtime environment to resolve the path for a program to use when it's different than pure system installed versions - i.e. /usr/bin/env python3 inside a venv for Python uses the virtualenv's python, but outside of that env on the bare system it's /usr/bin/python3. What's your intention with using env, to declare env variables? – Thomas Ward May 12 '22 at 01:58

Use the full path:

# pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY `pwd`/topspin-4.1.4-linux.sh
