I'm having problems with some application/x-executable files. They simply don't open. I've tried to click them and I've tried to open them in Terminal, but nothing happens. On Ubuntu 12.04, both of the programs work, just by double-clicking them.

The programs are:

  • fez (setup of Fez game; Humble Bundle edition)
  • supermeatboy (setup of the game; Humble Bundle edition)
  • fusion (executable file of the emulator Kega Fusion)

I've already installed the 32-bit libs (Fusion needs it).

I've tried this in Terminal:

bash: ./fez: No such file or directory

  • I did it. I swear. I know that the most of people who come here to ask questions are new in Linux and Ubuntu, but I'm not. I use Ubuntu since 12.04 version and I know how to use command lines in the Terminal. But I just can't open the executables. Is how i say: returns "No such file or directory". But the file is definitely there! Thanks for the help anyway! Sorry if look like I'm angry or whatever. I swear I'm not. Jul 28, 2014 at 23:31

  • Returns "Total 0" Jul 29, 2014 at 14:16
  • Could you please give the result of ls -la ~/Downloads (to have info about the folder itself .) and cat ~/.config/user-dirs.dirs (to check how are set Nautilus favorites)

I had an equivalent issue with an executable file called myExecutable. To work, you need the both following conditions :

  1. The file permission / right must be set as executable :

    • One way is to run the command : chmod +x myExecutable
    • Another way is to do it graphicaly with right clic on the file, property, permission
    • You can check it by looking at x with : ls -l
  2. The mounted file system / partition must allow to run an executable.

    Eg. the file system must be mounted with exec parameter instead of noexec. Look at the file /etc/fstab or check the mounted partition with mount command

Then, you will be able to run the file :

  • With double clic on it
  • Or in running in a console : ./myExecutable
