rpi-imager currently has no facility to encrypt the image it flashes to the storage on the Pi (and making such a facility generic enough that it would fit all potentially interested distros is a daunting task to say the least), so this isn't valid for rpi-imager.
I *did* add some initial steps towards this in the lunar desktop images, which preserve space at the end of the root partition for LUKS headers (by ensuring the root file-system doesn't expand *all* the way to the partition size) which should make this easier to achieve in future, but there's still plenty of work to be done here. ** Changed in: rpi-imager (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi in Ubuntu. https://bugs.launchpad.net/bugs/1959113 Title: missing built-in disk encryption at install time Status in Ubuntu: New Status in linux-firmware-raspi package in Ubuntu: New Status in linux-raspi package in Ubuntu: New Status in rpi-imager package in Ubuntu: Invalid Bug description: Is there a simple way to install Ubuntu on SD card for Raspberry Pi4 with full disk encryption?
