## Install the Electrum wallet on your desktop
**Warning: Electrum versions older than 3.3.4 are susceptible to phishing. Do not download Electrum from another source than electrum.org, and learn to verify GPG signatures.**
Follow the instructions on https://electrum.org/#download
### Linux desktop: install, configure and run the Electrum wallet
The instruction are in the script: [electrum_wallet.sh](electrum_wallet.sh)
Tested on Ubuntu 18.04.
To download and run on the Linux desktop:
`$ wget https://raw.githubusercontent.com/openoms/bitcoin-tutorials/master/electrs/electrum_wallet.sh && bash electrum_wallet.sh`
* #### Linux desktop: download, validate and run the Electrum wallet
The instruction are in the script: [electrum_wallet.sh](electrum_wallet.sh)

To download and run on the Linux desktop:
`$ wget https://raw.githubusercontent.com/openoms/bitcoin-tutorials/master/electrs/electrum_wallet.sh && bash electrum_wallet.sh`
### Connect the Electrum wallet to Electrs:
## Connect the Electrum wallet to Electrs
For an unencrypted TCP connection (only to be used inside a secure LAN):
`electrum --oneserver --server RASPIBLITZ_IP:50001:t`
* #### For an unencrypted TCP connection (only to be used inside a secure LAN)
`$ electrum --oneserver --server RASPIBLITZ_IP:50001:t`
To connect through SSL:
`electrum --oneserver --server YOUR_DOMAIN:50002:s`
* #### To connect through SSL
`$ electrum --oneserver --server YOUR_DOMAIN:50002:s`
After a reinstall will need to delete the SSL certificate from the Electrum data directory to be able to connect again to the same domain:
* on Linux delete the relevant file from the `~/.electrs/certs` directory
After a reinstall will need to delete the SSL certificate from the Electrum data directory to be able to connect again to the same domain:
* on Linux delete the relevant file from the `~/.electrs/certs` directory
* #### To connect through Tor (see [how to set up a Hidden Service](Tor_Hidden_Service_for_Electrs.md))
* Start electrum with the Tor Browser open (proxy on port 9150):
`$ electrum --oneserver --server Tor_address.onion:50001:t --proxy socks5:127.0.0.1:9150`
* With Tor installed and running (proxy on port 9050):
`$ electrum --oneserver --server Tor_address.onion:50001:t --proxy socks5:127.0.0.1:9050`
This works in [Tails](https://tails.boum.org/) too.
