'No such file or directory' error in bash, but the file exists?

Question

On Ubuntu, I get a 'No such file or directory' error when I try to execute a command.

I have checked with ls -la , the file adb is there and it has 'x' flag So why I am getting a 'No such file or directory'?

~/Programs/android-sdk-linux_x86/platform-tools$ ./adb
 bash: ./adb: No such file or directory
~/Programs/android-sdk-linux_x86/platform-tools$ ls -la

Answer 1

It's an executable file that misses required libraries. Use ldd to see what it needs, then provide these files.

Answer 2

Android SDK requires 32-bit libraries. You probably are on 64-bit and need the 32-bit libs. Here are the troubleshooting directions from developer.android.com

For Ubuntu 13.10 (Saucy Salamander) and above, install the libncurses5:i386, libstdc++6:i386, and zlib1g:i386 packages using apt-get:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386

For earlier versions of Ubuntu, install the ia32-libs package using apt-get:

apt-get install ia32-libs

Answer 3

sudo apt-get install --reinstall libc6-i386

is also need for me.

Answer 4

I was also seeing the same after switching my machine from 32 bit ubuntu to 64 bit. Bash would report 'No such file or directory' of files that clearly existed with the execute attribute.

sudo apt-get install --reinstall libc6-i386

Fixed the problem. These are the "GNU C Library: 32-bit shared libraries for AMD64"

Seems like this is a bug in bash. Note that I also changed the default shell from dash to bash using

sudo dpkg-reconfigure dash

before I tried running the 32 bit executable. So I'm not sure if the problem would have happened with the default dash shell

Answer 5

On a fresh Xubuntu 13.10 x64 install I got adb to run with:

sudo apt-get install --reinstall libc6-i386
sudo apt-get install libstdc++6:i386

And also zlib1g:i386 to make aapt work.

and if you still miss something use:

lld adb

Answer 6

For adb make sure you have the SDK unpacked and have run the SDK Manager to fully populate the SDK. Additionally make sure you have the following installed: A.) JDK 6 or better B.) lib32stdc++6 C.) lib32ncurses5

hoffmanc was the closest to getting it right, I don't really understand why the answer from Daniel Beck is marked as correct when it's not even close and has nothing to do with the problem.

Incidentally, if you try to run a truly non-existant command (i.e.:

# fakecommand

you'll get: fakecommand: command not found, whereas in your situation the output you are seeing is actually coming from adb even though it's not very clear that is the case.

Answer 7

Ubuntu seems to have some issues with LSB compatibility, so try this if you are on Ubuntu:

apt-get install lsb

Note that ldd will sort of show that all the libraries are there, but they are not.
