I cannot run an executable file, and it seems that all permissions, owner, etc. are correct. I don't understand the problem; I hope that someone will find a solution.
I'm logged as tux.
tux@tux-laptop:~/Data/Flightplan/FPP0.19Linux$ whoami tux
Here is the directory where the executable resides. The file that I'm trying to run is FP (the program is installed and owned by tux, FP is Flightplanpro for Linux)
tux@tux-laptop:~/Data/Flightplan/FPP0.19Linux$ ls -l total 113588 -rwxr-xr-x 1 tux tux 23807760 2013-05-30 19:26 FP
When I try to run FP, this happens:
tux@tux-laptop:~/Data/Flightplan/FPP0.19Linux$ ./FP bash: ./FP: Permission denied
I checked 100 times and I made sure that the flag "Allow executing file as program" is ON. Using sudo or root doesn't help; the permission denied error doesn't show up, but nothing happens.
tux@tux-laptop:~/Data/Flightplan/FPP0.19Linux$ sudo ./FP
I can run that program on my other Linux machine without any problem.
I'm running Ubuntu 11.10 (for various reasons including disc space, I cannot upgrade).
