Upgrading my RaspiBlitz Bitcoin and Lightning Node

My documentation of my RaspiBlitz 1.6.1 upgrade

I am a Windows user, I have some very basic BASIC knowledge. I know how to build websites with HTML, PHP and MySQL, but I am not a coder, so I do have difficulties using GitHub and how to handle the Command window or PuTTY. I set up my first RaspiBlitz at a Bitcoin Austria workshop in Feb 2020. This device was a present to Alakanani Itireleng and the Satoshicentre in Botswana. So I have set up a new RaspiBlitz for myself in July 2020 together with a friend from Bitcoin Austria, who also assisted me in the upgrade process. I could not have done that without these friends. But I am learning every time. The purpose of this documentation is to have a guide for the next upgrade for myself and maybe it is helpful for somebody else too.

The upgrade took about 3 hours in total. Maybe it can be less, because I wrote this article at the same time and had to communicate with my friend in between.

Official Documentation How To Upgrade

Open PuTTY and in the RaspiBlitz Main Menu go to UPDATE
it asks you to make a backup of your lnd data or you can skip
I did not skip, I made a backup of my lnd data
therefore it tells you to open a CMD window and enter:

scp -r 'admin@192.168.0.17:/home/admin/lnd-rescue-*.tar.gz' ./

This did not work, I had to remove the ‘ at the beginning and end

scp -r admin@192.168.0.17:/home/admin/lnd-rescue-*.tar.gz ./

Then this frightening message showed up
Upgrade RaspiBlitz
My friend told me to delete the known_hosts file. So I changed to the directory with

cd .. | Goes up one folder
cd users | Goes into folder users

and then
C:\Users\HP\.ssh>del known_hosts
Then I tried again

My reckless friend told me: YES so I put in yes

Result was another warning and the possibility to put in my Password A for the Raspiblitz, which starts the download

Then it lost connection and I started the download again.

This downloaded the data into the directory, where I put in the command. For instance:
C:\Users>scp -r admin@192.168.0.17:/home/admin/lnd-rescue-*.tar.gz ./

File is downloaded to C:/Users

After the download you can proceed in the PuTTY window with ENTER

It makes another backup to the SSD (or HDD)
And this screen follows:
Start Update

Choose START UPDATE – this powers the Raspiblitz down and you can take the SD card out of it and put it into your PC. Then you download the IMG file for the new upgrade from https://github.com/rootzoll/raspiblitz and flash the SD card with Balena Etcher.

With the new image you put the sd card back into the RaspiBlitz and turn it on.

Then it boots and reboots and starts to install services. This takes some hours. Afterwards you have to reset password A (you can take the same PW as you had before).
Finale Password reset

It shuts down and reboots a final time. This takes some minutes, before you have to enter password C. Then the node is syncing and finally up and running again. After about one minute all the lightning channels are here again.

In the RaspiBlitz the command to start the menu new is

raspiblitz
OR
/home/admin/00mainMenu.sh
