Linux - Cannot execute binary file

Question

I know this question has been asked a lot, but the problem remains fo me:

I have a 64bits ELF executable that I am trying to run on my Kali VM, but it keeps telling me that the file doesn't exist.

The solution most of the time for this problem is the difference of architecture, but my Kali is x86-64:

$ uname -m
  x86_64

like the file (named '8') that I am trying to execute:

file 8
8: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.27, BuildID[sha1]=0xf3b096c69086131b091d1805894fde4fae0537a0, stripped

EDIT: Error:

 $ chmod +x 8
 $ ./8
 bash: ./8: No such file or directory

EDIT 2 : lld:

linux-vdso.so.1 =>  (0x00007fffe37fe000)
libssl.so.1.0.0 => /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 (0x00007f680fac8000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f680f73c000)
libcrypto.so.1.0.0 => /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007f680f343000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f680f13f000)
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f680ef28000)
/lib/ld-linux-x86-64.so.2 => /lib64/ld-linux-x86-64.so.2 (0x00007f680fd49000)

I tried to install the 32 bits library to be sure, but it didn't solve anything neither. I also tried it on my Ubuntu, same issues.

Has anybody an idea on ho to run it ? Here is a link to it if some of you want to try on other architectures: https://www.dropbox.com/s/s3ucka4ufd00zmy/8?dl=0

Done - I don't understand why people downvotes question so quickly... — P1kachu

Does ls . work correctly in that directory? We don't need the actual output, just success/failure. — Ignacio Vazquez-Abrams

bash: ./8: No such file or directory

This is caused by the file having an elf interpreter which is not installed on your system.

You can find out which elf interpreter your file is compiled with by running

readelf -l ./8 | grep interpreter

I am guessing that you have /lib/ld-linux-x86-64.so.2 compiled in, whereas the standard 64-bit elf interpreter is /lib64/ld-linux-x86-64.so.2.

The best fix is to correct the build script for your executable (it has something like -Wl,--dynamic-linker=/lib/ld-linux-x86-64.so.2 in it).

Alternatively, creating a symlink:

sudo ln -s /lib64/ld-linux-x86-64.so.2 /lib

will also fix the problem.

I tried sudo ln -s /lib64/ld-linux-x86-64.so.2 lib but it didn't work for me. Any other thoughts? I have the same problem as with the first guy asking the question.

@warfreak92 Your problem may look very similar, but may be subtly different. You should ask a separate question, and provide your exact details.

alright, @Employed Russian, I opened another question here: superuser.com/questions/1266195/…
