    Requirements and scope

    • x86_64 system with UEFI firmware
    • Secure Boot must currently be disabled
    • Legacy BIOS/CSM is not supported
    • This remains a prerelease intended for broader testing, not a stable production release

    UrsaOS v0.1.0-alpha.2 Stable

    spalencsar released this 2026-07-29 08:43:38 +02:00 | 22 commits to main since this release

    UrsaOS v0.1.0-alpha.2

    This development preview replaces alpha.1 for new installations.

    Fixed

    • Fresh installations now create a persistent Pacman keyring instead of retaining the temporary live keyring. This prevents unknown trust failures during official Arch package transactions.
    • ursaos-installer now declares Python as a direct runtime dependency.
    • ISO builds rebuild stale UrsaOS packages and reject a Calamares binary with unresolved runtime libraries before creating an image.

    Validation

    • The release ISO boots through both UEFI GRUB and BIOS Syslinux.
    • The BIOS/MBR installation path completed installation, reboot, tuigreet login and the branded Niri+DMS desktop during development testing.
    • The installed BIOS target completed sudo pacman -Syu successfully.

    Known limitations

    • This remains an early development preview and is not intended for production use.
    • Timeshift and no-snapshot installations have less end-to-end coverage than the default Btrfs + Snapper path.
    • Hardware coverage is still limited.

    Verify the ISO with the accompanying .sha256 file before use.

    UrsaOS v0.1.0-alpha.1 Stable

    spalencsar released this 2026-07-28 14:54:30 +02:00 | 24 commits to main since this release

    UrsaOS v0.1.0-alpha.1

    Warning

    Known installer issue: Systems installed from this image inherit the
    temporary live Pacman keyring. Official Arch package transactions can then
    fail with unknown trust. Alpha.1 should therefore not be used for a fresh
    installation unless the manual repair below is accepted.

    Fix for systems installed with alpha.1

    Run the following commands in the installed system:

    sudo rm -rf /etc/pacman.d/gnupg
sudo pacman-key --init
sudo pacman-key --populate archlinux
sudo pacman -Syu

    This removes the copied live keyring, creates a persistent local Pacman master
    key and imports the trusted Arch Linux package-signing keys again.

    Fix status

    The installer has been corrected in ursaos-installer 0.1.0-11. New
    installations will create their own persistent Pacman keyring automatically.
    The correction will be included in the next UrsaOS release; the alpha.1 ISO
    itself remains affected.

    The first public UrsaOS development preview provides a graphical Try & Install
    live system based on Arch Linux with Niri and Dank Material Shell.

    Highlights

    • Branded German and English UEFI GRUB and BIOS Syslinux live boot entries
    • Complete Niri + DMS live desktop without an automatically opened terminal
    • Calamares live-copy installation with Btrfs as the automatic default
    • Installer choice between Snapper, Timeshift and no snapshot manager
    • Branded GRUB, tuigreet login and UrsaOS desktop session
    • Archinstall retained as an advanced online fallback

    Validated path

    The UEFI path has completed repeated end-to-end tests through live boot,
    Calamares installation with Btrfs + Snapper, reboot, GRUB, tuigreet login and
    the Niri+DMS desktop.

    Known limitations

    • This is an early development preview and is not intended for production use.
    • Legacy BIOS end-to-end installation is not yet validated.
    • The Timeshift and no-snapshot installer choices have not received the same
      end-to-end coverage as the default Snapper path.
    • Hardware coverage currently focuses on QEMU/KVM virtual machines.
