#### Perform the following steps on both your online and offline computers: Install required Debian/Ubuntu packages: $ sudo apt-get install autoconf git libgmp-dev libssl-dev libpcre3-dev libtool wipe curl $ sudo apt-get install python3-dev python3-ecdsa python3-pexpect python3-setuptools python3-cryptography python3-nacl python3-pip python3-gmpy2 python3-sha3 python3-requests python3-aiohttp python3-socks Using the [pip3][P] installer, install the scrypt Python package: $ sudo -H pip3 install scrypt Install the secp256k1 library: $ git clone https://github.com/bitcoin-core/secp256k1.git $ cd secp256k1 $ ./autogen.sh $ ./configure $ make $ sudo make install $ sudo ldconfig $ cd .. Install MMGen: $ git clone https://github.com/mmgen/mmgen.git $ cd mmgen $ git checkout stable_linux # see 'Note' below $ ./setup.py build $ sudo ./setup.py install # see 'Testing Note' below $ cd .. **Note:** if you want to use features that have appeared since the latest `stable_linux` release, then you can omit the `git checkout` step and remain on the `master` branch. Please bear in mind, however, that while the tip of `master` is always tested on Linux before being pushed to the public repository, security vulnerabilities are more likely to be present in new code than in a stable release. In addition, new code may require dependencies or installation steps not yet covered in the documentation. **Testing Note:** MMGen may be tested in place prior to installation. Refer to the [Test Suite][ts] wiki page for details. Install your coin daemon(s). To install prebuilt binaries, go [here][01]. To install from source, go [here][02]. #### *Note for offline machines:* > Your offline machine must be connected to the Internet to retrieve and install > the above packages as described above. This is normally not a problem, as you > can simply take the machine offline permanently after the install is done, > preferably removing or disabling its network interfaces. > However, if your machine is already offline and you wish to leave it that way, > or if it lacks a network interface entirely, then you’ll need to take roughly > the following steps: >> If your offline and offline machines have the same architecture, then you can >> download the Debian/Ubuntu packages and their dependencies on your online >> machine using `apt-get download`. Otherwise, you must retrieve the packages >> manually from `packages.debian.org` or `packages.ubuntu.com`. >> >> Download any required Python packages using `pip3 download`. >> >> Transfer the downloaded files and cloned Git repositories to your offline >> computer using a USB stick or other removable medium. Install the >> Debian/Ubuntu packages with `sudo dpkg -i` and the Python packages with `pip3 >> install`. Install MMGen and the secp256k1 library from the copied Git >> repositories as described above. Congratulations, your installation is now complete!
