Evan's debugger (edb) - Failed to open and attach to process: execv() failed: No such file or directory

Question

Problem:

When I try to open an executable (in this case exploit exercises protostar stack0), then the following message appears in a pop-up box:

Failed to open and attach to process: execv() failed: No such file or directory.

and I am unable to open any files because of this.

Terminal output:

osboxes@osboxes:~/tools/edb-debugger/build$ ./edb --run ~/proto/bin/stack0 
Icon theme "elementary" not found.
Starting edb version: 1.1.0

Terminal process has TTY:  "/dev/pts/5"

At first I installed edb using apt-get. This problem occurred. Then I uninstalled and installed it manually from the source code (and fixed the segmentation fault issue by changing the plugins directory). The problem remains. It doesn't matter if I use --run or try to open it from the GUI.

Version info

I'm using Lubuntu. Linux 5.3.0-18. It's a VM downloaded from OSBoxes.

Answer 1

osboxes@osboxes:~/proto/bin$ ll | grep stack0
-rwsr-xr-x 1 root    root    22412 Jan 22 07:16 stack0*
osboxes@osboxes:~/proto/bin$ ./stack0
bash: ./stack0: No such file or directory

The program is marked as executable, but trying to execute it says there is no such file or directory. I didn't even notice it, because radare2 and gdb were able to execute it.

After reading stackoverflow 1 and stackoverflow 2, it seems that the problem is that my 64 bit system can't handle the 32 bit executable.

After running the following command, I got the executable to work. sudo apt-get install lib32z1

And also edb started working.

Edit: Another reason why it might not work for you is that you have not marked it as executable. In that case:

chmod +x filename
