How to update your Raspberry Pi node

SSH into your Raspberry Pi using the following command:

ssh myst@ip-of-your-raspberry

The default password is mystberry.

Then to update your RPI, run:

How to update your Docker node

In order to update your Docker node, run the following commands.

Note 1: Make sure that you have your data in the persistent storage like myst-data.

Note 2: You can backup your keys before trying to update node version FAQ.

Pull the latest node image.

docker pull mysteriumnetwork/myst

Delete the container that is already being used for running node:

docker rm -f myst

Follow the running a docker node guide to start a new container.

How to setup automatic node updates on Ubuntu/Debian/RaspberryPi

Install the unattended-upgrades package

The unattended-upgrades package can be configured to perform unattended upgrades to install updated packages and security updates automatically. To install the unattended-upgrades package along with a package to identify the changes, enter the following in your terminal:

sudo apt -y install unattended-upgrades apt-listchanges

Configure unattended-upgrades

Unattended-upgrades

The unattended-upgrades config file location is /etc/apt/apt.conf.d/50unattended-upgrades. Lines starting with a double slash // have no effect. Therefore, to “enable” a line, remove the double slash //.

Allowing automatic node updates on RaspberryPi

Edit the 20auto-upgrades configuration file:

sudo nano /etc/apt/apt.conf.d/20auto-upgrades

and your configuration file should look like this:

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "7";
APT::Periodic::Unattended-Upgrade "1";

Edit the 50unattended-upgrades configuration:

sudo nano /etc/apt/apt.conf.d/50unattended-upgrades

and your configuration file should look like this:

Unattended-Upgrade::Origins-Pattern {
        "origin=Raspbian,codename=${distro_codename},label=Raspbian";
        "origin=Raspbian,codename=${distro_codename},label=Raspbian-Security";
        "o=LP-PPA-mysteriumnetwork-node";
};

Unattended-Upgrade::AutoFixInterruptedDpkg "true";
Unattended-Upgrade::Remove-Unused-Kernel-Packages "true";
Unattended-Upgrade::Remove-Unused-Dependencies "true";
// Automatically reboot *WITHOUT CONFIRMATION* if
//  the file /var/run/reboot-required is found after the upgrade
Unattended-Upgrade::Automatic-Reboot "true";
// Automatically reboot even if there are users currently logged in
// when Unattended-Upgrade::Automatic-Reboot is set to true
Unattended-Upgrade::Automatic-Reboot-WithUsers "true";

Allowing automatic node updates on Ubuntu/Debian

The section that controls what packages are updated automatically starts with Unattended-Upgrade::Allowed-Origins {. You can enable all packages or security updates only. For software that is not on the Ubuntu repos that you would like to update, you need to add an origin and archive to the file. To find what those are for your PPAs, open the folder /var/lib/apt/lists/, that is the storage area for state information for each package resource and look for the file that end with Release in the name. Navigate to this file.

Inside you will see something like the following:

ppa

The origin is (Origin: LP-PPA-mysteriumnetwork-node-mainnet) and the archive will be whatever is under the line Suite (Suite: focal).

Now edit /etc/apt/apt.conf.d/50unattended-upgrades to include it:

// Automatically upgrade packages from these (origin:archive) pairs
//
// Note that in Ubuntu security updates may pull in new dependencies
// from non-security sources (e.g. chromium). By allowing the release
// pocket these get automatically pulled in.
Unattended-Upgrade::Allowed-Origins {
        "${distro_id}:${distro_codename}";
        "${distro_id}:${distro_codename}-security";
        // Extended Security Maintenance; doesn't necessarily exist for
        // every release and this system may not have it installed, but if
        // available, the policy for updates is such that unattended-upgrades
        // should also install from here by default.
        "${distro_id}ESMApps:${distro_codename}-apps-security";
        "${distro_id}ESM:${distro_codename}-infra-security";
//      "${distro_id}:${distro_codename}-updates";
//      "${distro_id}:${distro_codename}-proposed";
//      "${distro_id}:${distro_codename}-backports";
        "LP-PPA-mysteriumnetwork-node-mainnet:focal";
};

unattended-ugprades is running automatically and is called via cronjob. If you want to debug it, you can easily run it with parameter: 

sudo unattended-upgrades -d
