Why can't I run this file that definitely exists?

Hi ,

take a look at this : http://www.youtube.com/watch?v=Gn6sBs_s9O0

I hope it helps you to figure it out.

Thanks

OR

maybe first you must do the file executable by giving the correct rights.

chmod a+x Downloads/spaz-linux-humblebundle-09182012-bin

and then run with

cd Downloads
./spaz-linux-humblebundle-09182012-bin

Thanks

The file is already executable. Here are the permissions.

-rwxr-xr-x 1 asa asa 157466422 Sep 19 21:07 ./spaz-linux-humblebundle-09182012-bin

I've tried the software center for previous humble games and it's always been totally unstable requiring several attempts to install each game. My question is less about how do I install spaz but more about why is it I have a completely valid file that Ubuntu refuses to run. If it's happening here it will happen with something else.

The file command shows it is an executable file, my ls shows that it has the execute permission and the file exists.

Can you give the output of:

lsb_release -a; uname -a

Thanks

You are trying to use a 32bit file in a 64bit OS. Is there not a 64bit binary for the file?

There is not, but it does run on a different 64-bit machine of mine with an older version of Ubuntu. Here is the lsb_release -a; uname -a for the machine where the exact same file does run.

Try:

chmod +x ~/Downloads/spaz-linux-humblebundle-09182012-bin
sudo ~/Downloads/spaz-linux-humblebundle-09182012-bin

Does it now run? If not, what is output?

Thanks

Initially I thought this could be some kind of security change on the Kernel. I thought the kernel might detect foreign files and not run them similar to how Windows detects downloaded files and prompts. This doesn't seem to be the case though as I was able to install Rochard by downloading an running it. I almost filed a bug against BASH but then I tested and DASH has the same issue. My other other suspect has been the filesystem, nothing odd there:

asa@asa:~/Downloads$ mount
/dev/sdb2 on / type ext4 (rw,errors=remount-ro)
... SNIP ...
/dev/sda1 on /home type ext4 (rw)

can you give the output of:

ls ~/Downloads

Thanks

I think you're on to something with it being 32-bit. I just downloaded the binaries for Super Meat Boy, Windosil, and Avadon. All 3 use 32-bit installers and have the same problem. I also went and checked Rochard and it's a 64-bit binary.

Thank you so much for your help. I tried installing ia32-libs and now it works. I've not marked the problem as Solved though because I'd really like to file a bug report so that people get some kind of "ia32-libs missing" error instead of the totally false "no such file or directory" error. Do you have any idea where this bug report should go? The kernel? Not sure about reporting it against ia32-libs since the problem results from it not being installed.

Thanks Sam_, that solved my question.

This definitely has nothing to do with nautilus as it was never involved. Maybe you selected the wrong package?

Asa Ayers, no idea who assigned the question to nautilus, I've assigned it yesterday to ia32-libs.
