The following were tested in Ubuntu 14.04, Ubuntu 16.04 and Ubuntu 18.04, some dependencies can be different in other distros

• aptitude update -y && aptitude upgrade -y && apt-get update -y && apt-get upgrade -y && apt-get dist-upgrade -y
• dd if=/dev/zero of=/swapfile bs=1M count=4096
• mkswap /swapfile
• swapon /swapfile
• echo "/swapfile swap swap defaults 0 0" >> /etc/fstab
• sudo apt-get install build-essential libssl-dev libboost-all-dev libdb5.3 libdb5.3-dev libdb5.3++-dev libtool automake libevent-dev bsdmainutils -y
• sudo apt-get install git ntp make g++ gcc autoconf cpp ngrep iftop sysstat autotools-dev pkg-config libminiupnpc-dev libzmq3-dev -y
• git clone https://github.com/groestlcoin/groestlcoin
• cd groestlcoin
• ./autogen.sh
• ./configure
• make
• strip src/groestlcoind src/groestlcoin-cli src/groestlcoin-tx

  listen=1
  server=1
  maxconnections=865
  daemon=1
  rpcuser=yourusernamehere
  rpcpassword=yourpasswordhere
• Crtl+o enter, ctrl X
• groestlcoind
• Let it sync (can take up to 2 hours), verify with groestlcoin-cli getnetworkinfo
• cd contrib/linearize/
• cp example-linearize.cfg linearize.cfg
• nano linearize.cfg and edit input= and output_file= to match the right existing path otherwise you will get premature end of data error
• ./linearize-hashes.py linearize.cfg > hashlist.txt
• ./linearize-data.py linearize.cfg
• Bootstrap.dat can be found in ~/.groestlcoin
