Getting “Command not found” when trying to execute mounted file

Question

I’m not able to execute the files in a mounted directory in my Ubuntu 16.04 VM. I get the error “command not found”:

dseltz-VirtualBox:/local> ls -al /nfs/local/gnu/i86Linux2.0/bin/makeheader

-rwxr-xr-x 1 systemd-network uucp 49379 Oct 20 1999 /nfs/local/gnu/i86Linux2.0/bin/makeheader

dseltz-VirtualBox:/local> /nfs/local/gnu/i86Linux2.0/bin/makeheader /nfs/local/gnu/i86Linux2.0/bin/makeheader: Command not found.

My VM is a x64 running Ubuntu 16.04 and so is the mounted system.

I looked at the mounts and don’t see the noexec property(on either system).

Here is the mount command:

sudo mount -o exec 10.15.1.203:/local /nfs/local

I made sure my users matched on my VM machine and the build system.

Any ideas what I'm doing wrong?

It looks like you mounted at /nfs/local but are trying to run a file that is in absolute path /local — steeldriver, Feb 02 '17 at 13:49
What is the output of file /local/gnu/i86Linux2.0/bin/makeheader ? — Satō Katsura, Feb 02 '17 at 13:59
I have a logical link from /nfs/local to /local: sudo ln -s /nfs/local / From either location the error is "Command not found" — David Seltz, Feb 02 '17 at 15:04
dseltz-VirtualBox:/local> file /nfs/local/gnu/i86Linux2.0/bin/makeheader /nfs/local/gnu/i86Linux2.0/bin/makeheader: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, not stripped — David Seltz, Feb 02 '17 at 15:07
No it does not exist. It does exist on another Ubuntu 16.04 system where the same mounted executable work. — David Seltz, Feb 02 '17 at 16:01

With the help of the comment from Kusalananda I found that I needed to add i386 architecture to run my 32-bit packages:

sudo dpkg --add-architecture i386
sudo apt-get update
apt-get install libc6:i386
apt-get install libgtk2.0-0:i386

your can do the install in one: apt-get install libc6:i386 libgtk2.0-0:i386 – ctrl-alt-delor Feb 02 '17 at 23:19
