fluxgui not an executable format

  • F.lux is a wonderful program, but there is issues with it on Linux Mint. I currently run Linux Mint 17.2 (Cinnamon) (64-bit), and fluxgui doesn't seem to be working anymore. It use to for a while then it just stopped.

    I tried to run a debug with GDB in the terminal console, but I don't get much out of it.

    $ gdb fluxgui >> fluxgui_GDB_dump

    (gdb) run

    (gdb) exec-file /usr/bin/fluxgui
    "/usr/bin/fluxgui": not in executable format: File format not recognised
    (gdb) xflux -k 2700 -l -33.8800 -g 151.1914

    second output shows this;

    "/usr/bin/fluxgui": not in executable format: File format not recognised
    Starting program: /usr/bin/xflux 
    [Inferior 1 (process 26102) exited normally]

    It tells me there that fluxgui is not in executable format and not recognised. The files are executable however;

    $ ls -la /usr/bin/fluxgui /usr/bin/xflux
      -rwxr-xr-x 1 root root    877 Sep  8  2010 /usr/bin/fluxgui
      -rwxr-xr-x 1 root root 527224 Sep  8  2010 /usr/bin/xflux

    also I do notice that fluxgui even when exited normally it may leave behind it's PID file under /tmp directory.
