Ethereum: Why do you get the “bitcoin: command not found” error on Ubuntu?

The dreaded “command not found” error! If you experience this problem on your Ubuntu desktop, you are not alone. This problem can appear even if you have successfully compiled Bitcoin and installed the necessary libraries using apt-get.

In this article, we will explore why you may be getting “bitcoin: command not found” errors on Ethereum and how to resolve them.

Why does it happen?

The “bitcoind” command is part of the Bitcoin software that allows you to manage the Bitcoin network. In order to run “bitcoind,” your system needs to know where to find it. On Ubuntu, it is usually located in “/usr/bin.”

When you have compiled and installed Bitcoin with apt-get, the package manager has added the binary to its list. However, the package database may not have been updated yet.

The Problem: Binary Location

bitcoind is located in /usr/local/bin, not /usr/bin. It may seem obvious, but you’d be surprised how often this error can occur.

To fix the error, you need to update the package list and then reinstall bitcoin. Here’s a step-by-step guide:

Update the Package List

• Open a terminal on your Ubuntu desktop.

• Run the following command: sudo apt-get update

• Press Enter to run the command.

Reinstall bitcoind

After updating the package list, you can reinstall bitcoin with the following command:

sudo apt-get install bitcoin-full

Note that this command will overwrite any existing bitcoin configuration files. If you want to keep your current configuration, use the -y flag (e.g. sudo apt-get install bitcoin-full -y).

Verify the installation

Once bitcoin is installed and configured correctly, try running it again:

cd src
bitcoind -daemon

This should resolve the command not found error.

Additional Tips

• Make sure you have also updated your system’s package cache using sudo apt-get upgrade. This ensures that all dependencies are up to date.

• If you are still having issues, try running apt-cache policy bitcoin to verify that the package is installed correctly. You can use this command to check for updates in the package index.

By following these steps, you should be able to resolve the bitcoin: command not found error on Ethereum and start compiling and using Bitcoin on your Ubuntu desktop.
