FullPageOS 1.0.0 RC1 Status

[guysoft]

FullPageOS 1.0.0 first release candidate.

This release moves FullPageOS forward to Raspberry Pi OS Trixie and starts publishing two primary images: armhf and arm64. The old no-acceleration variant is being dropped for this release.

Please test and report if there are any problems.

Tag: 1.0.0-rc1 (d08eb72)

Features

• Chromium Version 148.0.7778.167
• Raspberry Pi OS 2026-04-21
• Debian Trixie
• armhf and arm64 image builds
• The Chromium package is now chromium instead of chromium-browser, matching current Raspberry Pi OS packages
• Added Chromium startup handling to prevent the low-memory warning dialog from blocking boot until a mouse is connected (Thanks @mhowe91)
• Added QEMU-based end-to-end testing for FullPageOS boot, dashboard serving, and Chromium kiosk display
• E2E builds now use the shared CustomPiOS reusable workflow and ghcr.io/guysoft/custompios:devel

Changes since 0.14.0

FullPageOS:

• Fixed Limit chromium disk-cache-size to 500Mb #613 and Fix for chromium BrowserMetrics filling filesystem: '/dev/mmcblk0p2' Disk Full, '/home/pi/.config/chromium/BrowserMetrics' fills entire disk, chromium will not load, FullPageOS logo shows. Also fix for Also add fix for changing hostname (clear chromium/Singleton*) #612
• Renamed Chromium usage from chromium-browser to chromium for Trixie compatibility Rename chromium-browser to chromium, package was renamed in latest Pi OS #696 (Thanks @grivkees)
• Added Chromium --no-memcheck so the low-memory warning dialog no longer blocks boot until a mouse is connected Low memory error popup on Pi Zero 2 W prevents boot #672 (Thanks @mhowe91)
• Added an E2E test suite that boots the image in QEMU and validates SSH, lighttpd, and Chromium kiosk display
• Added armhf and arm64 CI build matrix entries
• Fixed E2E boot/display issues around Xvfb, matchbox, SSH background processes, and diagnostics
• Refactored E2E to use the CustomPiOS multi-stage test container and reusable workflow
• Repointed E2E back to CustomPiOS devel after the required CustomPiOS fixes landed

CustomPiOS:

• Added Trixie compatibility fixes for missing policykit-1, deprecated SSH IPQoS, and libconfig package changes
• Improved BASE_BOARD and variant/config.local handling, including arm64 board selection
• Fixed QEMU static binary selection and added test coverage for host/target architecture combinations
• Added the shared distro E2E testing framework, QEMU boot orchestration, hooks, and SSH helpers
• Added the reusable e2e-test.yml workflow used by FullPageOS
• Fixed E2E SSH on Trixie by setting the pi shell to /bin/bash
• Seeded passwordless sudo for the pi user in prepared test images so post-boot hooks can run non-interactively
• Added shared browser screenshot helpers for distro E2E artifacts

Build and E2E verification

Latest verified successful build:
https://github.com/guysoft/FullPageOS/actions/runs/26561247778

Jobs:

• build (raspberrypiarmhf, armhf) passed
• build (raspberrypiarm64, arm64) passed
• e2e-test / e2e-test passed

The E2E job downloads the arm64 image from the build job, boots it under QEMU, waits for SSH, runs the FullPageOS tests (lighttpd dashboard, Chromium kiosk), and uploads logs + a screenshot of the running session as artifacts.

Download

These images are also selectable in Raspberry Pi Imager under the
"FullpageOS (RC)" entry. The primary host is unofficialpi.org; the same zips
are mirrored on the GitHub pre-release
(identical files, identical checksums).
