  • make sure the system is up-to-date
sudo apt-get update

https://electrum.org/#download

  • Download package:

    $ wget https://download.electrum.org/3.3.4/Electrum-3.3.4.tar.gz

  • Verify Electrum's downloaded source code

    At this stage, we are ready to verify Electrum's source code. The source code is signed by Thomas Voegtlin (https://electrum.org).
    Let's import his public key:

    $ gpg --keyserver pool.sks-keyservers.net --recv-keys 2BD5824B7F9470E6

    gpg: key 2BD5824B7F9470E6: public key "Thomas Voegtlin (https://electrum.org) " imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg:               imported: 1

  • Confirm a correct key import and proceed to verify the downloaded file with the help of the signature file:

    $ wget https://download.electrum.org/3.3.4/Electrum-3.3.4.tar.gz.asc

      `$ gpg --verify Electrum-3.3.4.tar.gz.asc`

    gpg: Signature made Tue 12 Dec 2017 17:06:09 AEDT
gpg:                using RSA key 2BD5824B7F9470E6

Electrum Personal Server

Follow Stadicus`s guide: https://github.com/Stadicus/RaspiBolt/blob/master/raspibolt_64_electrum.md

some permissions I needed to fix:

ssh admin@Raspibolt

sudo su - bitcoin

ls -la

drwx------ 6 bitcoin bitcoin 4096 Jan 2 23:55 .local

chmod 755 .local

drwxr-xr-x 6 bitcoin bitcoin 4096 Jan 2 23:55 .local

monitor the log:

tail -f /tmp/electrumpersonalserver.log

restrict Electrum to use your own EPS, point it to the LAN IP of your Raspibolt

python3 run_electrum --oneserver --server [RaspiBolt.IP]:50002:s
