Solving the Mysterious “armhf: openssl-libcrypto-fix: cannot execute binary file: Exec format error”

Are you tired of encountering the frustrating “armhf: openssl-libcrypto-fix: cannot execute binary file: Exec format error” message? Do you feel like you’ve tried every possible solution, only to end up back at square one? Fear not, dear reader, for you’ve stumbled upon the ultimate guide to resolving this pesky issue once and for all!

What’s the Deal with armhf and OpenSSL?

Before we dive into the solution, let’s take a step back and understand the players involved. armhf is an instruction set architecture (ISA) used by ARM-based systems, such as certain Linux distributions and embedded devices. OpenSSL, on the other hand, is a popular cryptography library used for secure communication over the internet.

The error message we’re targeting typically occurs when there’s a mismatch between the architecture of the system and the binary format of the OpenSSL library. In our case, the system is unable to execute the binary file due to an Exec format error, which can be attributed to the armhf architecture not being compatible with the OpenSSL binary.

Identifying the Problem

Before we can fix the issue, we need to pinpoint the root cause. Here are some common scenarios that might lead to the “cannot execute binary file: Exec format error” message:

• Running an x86-64 binary on an armhf system.
• Using an outdated or incompatible version of OpenSSL.
• Corrupted or incomplete installation of OpenSSL.
• Insufficient permissions or access rights.

If you’re unsure about the exact cause, don’t worry! We’ll cover each possible solution in this article.

Solution 1: Installing the Correct OpenSSL Version

Let’s start with the most obvious solution: ensuring you have the correct version of OpenSSL installed.

sudo apt-get update
sudo apt-get install libssl-dev

This command will update your package list and install the development package for OpenSSL, which includes the necessary libraries for armhf systems.

Verifying the Installation

After installing the correct version of OpenSSL, let’s verify that the installation was successful:

openssl version

This command should output the version of OpenSSL installed on your system. If you still encounter issues, move on to the next solution.

Solution 2: Compiling OpenSSL from Source

Sometimes, the pre-compiled binaries might not work as expected. In this case, we can try compiling OpenSSL from source:

wget https://www.openssl.org/source/openssl-1.1.1g.tar.gz
tar -xvf openssl-1.1.1g.tar.gz
cd openssl-1.1.1g
./config
make
make install

This code snippet downloads the OpenSSL source code, extracts it, and compiles it from scratch. The `./config` command configures the build process for the armhf architecture.

Verifying the Compilation

After compiling OpenSSL from source, let’s verify that the installation was successful:

openssl version

This command should output the version of OpenSSL installed on your system. If you still encounter issues, move on to the next solution.

Solution 3: Fixing Permissions and Access Rights

Sometimes, the error message can be attributed to insufficient permissions or access rights. Let’s fix that:

sudo chmod 755 /usr/lib/openssl/engines/libcrypto.so.1.1
sudo chown root:root /usr/lib/openssl/engines/libcrypto.so.1.1

This code snippet sets the correct permissions and ownership for the libcrypto.so.1.1 file, which is required for OpenSSL to function properly.

Solution 4: Disabling armhf Multiarch

In some cases, the armhf multiarch feature might cause conflicts with OpenSSL. Let’s try disabling it:

sudo dpkg --remove-architecture armhf
sudo update-alternatives --remove openssl

This code snippet removes the armhf architecture from the package manager and updates the alternatives for OpenSSL.

Solution 5: Reinstalling OpenSSL

As a last resort, let’s try reinstalling OpenSSL:

sudo apt-get purge openssl
sudo apt-get autoremove
sudo apt-get install openssl

This code snippet purges the existing OpenSSL installation, removes any unnecessary dependencies, and reinstalls OpenSSL.

Conclusion

And there you have it! Five comprehensive solutions to tackle the “armhf: openssl-libcrypto-fix: cannot execute binary file: Exec format error” issue. By following these steps, you should be able to resolve the problem and get OpenSSL working smoothly on your armhf system.

Remember, if you’re still encountering issues, it’s essential to provide detailed error messages and system information to help troubleshoot the problem further.
