Ledger Nano App


#1

I want to use Ledger Nano App, but have to use within Google Chromium. Is this secure? Anyone have experience using this in PureOS


Electrum + Ledger Nano S not recognized
#2

Well using ledger on linux might be tricky (require some steps in command-line / additional software installation) as you can see at:


and in: (installation of packages required for using Electrum wallet with ledger)

Regarding secure what is the question?

Assuming you already have Chromium installed…if not…

$ apt-get install chromium

This tended to work for me on PureOS:

$ wget -q -O - https://www.ledgerwallet.com/support/add_udev_rules.sh | sudo bash

However, it seems that every once in a while, Chromium doesn’t load correctly, so you need to run this if the browser does not start correctly:

$ chromium --disable-extensions

It’ll then load Chromium without extension support. Then close Chromium and reopen normally (without the disable extension flag). It should have the Ledger Apps/Extension support now (note, you need the Chromium Apps installed too which is available from the Ledger Wallet site: https://www.ledgerwallet.com/apps).

This happens to me on/off, so I have to sometimes run it with disabled extension support first, then reopen Chromium as I’ve mentioned above every time I want to use it. I noticed too, Chromium has a problem loading the libcanberra gtk module, so if you do this, it should help:

$ sudo apt-get install libcanberra-gtk*

From a software perspective, this is all I needed to do to get it working.

From a hardware perspective, you need to disable browser support for some reason for it to work. Your device also needs to be in “Use wallet to view accounts” mode else the Chromium App will not initialize it correctly.

I hope this helps.


Note, if you use Google’s Chrome version you don’t have this app/extension problem. But that kind of defeats the purpose of using an Open Source browser.

I prefer to use the Electrum app instead of the chrome app once the device is set up.
Follow the install instructions from Electrum.org.
Use the udev link previously posted.
Also follow this guide. https://support.ledgerwallet.com/hc/en-us/articles/115005161925
Of note, if you are using a segwit wallet on your ledger you’ll need to change the root path to 49’/0’/0’/ from 46.
Also the final part of the instructions has you run pip install btchip-python. This should be pip3 install btchip-python.
