Ubuntu 24.04

From the comments: "These exact instructions are not working on Ubuntu 24.04. Ubuntu has changed the naming of ZFS partitions, partition 2 and 3 are switched around, and the boot/efi folder is now different."

I don't have my dual-disk test system any longer, and so can't adjust these steps myself.

Overview

Ubuntu Desktop 20.04 supports a single ZFS boot drive out of the box. I wanted a ZFS mirror, without going through an entirely manual setup of Ubuntu as described by OpenZFS in their instructions for Ubuntu 20.04 and instructions for Ubuntu 22.04

Protonmail on CentOS server

#protonmail #centos #fedora #linux

Before you start

Currently protonmail bridge for linux is distributed as part of an open beta program, but soon it will be made public (https://protonmail.com/bridge/install).

Consider that the bridge linux client requires a paid protonmail account to work.

Get the protonmail bridge linux installer

Safest way to clean up boot partition - Ubuntu 14.04LTS-x64, Ubuntu 16.04LTS-x64

Reference

Case I: if /boot is not 100% full and apt is working
