    COSMIC on trial next to Plasma, and better tools for containers.

    What's new

    • COSMIC, on trial. System76's COSMIC desktop is installed next to KDE Plasma. Pick it from the session menu on the login screen; Plasma stays the default, and Plasma Login stays the login screen. The COSMIC session gets Kinetic's apps in its dock, skips COSMIC's own first-run setup (Plasma Setup has already done it), and keeps KDE's Xwayland video bridge out of COSMIC sessions. COSMIC still uses its own look and shortcuts
    • Podman Desktop, to manage rootless Podman containers, distrobox boxes, and Docker Engine's containers in one window. Anonymous usage data and its own update checks are off; dnf updates it
    • DistroShelf, a graphical manager for distrobox: create, enter, and upgrade boxes, and add their apps to the menu
    • Both apps ship as RPMs built by Kinetic, not Flatpaks, and a weekly check proposes updates when upstream releases

    Upgrading from 0.2.x

    dnf upgrade brings the system to 0.3.0, but new packages need installing once:

    sudo dnf upgrade --refresh
    sudo dnf install kinetic-cosmic podman-desktop distroshelf
    

    Coming from 0.2.0 with the old GitHub Pages repository? Point the system at codevault first, as in the 0.2.1 notes:

    sudo dnf install https://codevault.sh/api/packages/zypher-systems/rpm/fedora-44/package/kinetic-repos/0.1.0-2.fc44/noarch
    

    Verifying the ISO

    The checksum file is signed with the ZypherOS key, fingerprint 098E 710A DBE3 FEE4 351B 44F4 0EE4 C89F 7AE0 182E (in the repo at packages/kinetic-repos/keys/RPM-GPG-KEY-zypheros):

    gpg --import RPM-GPG-KEY-zypheros
    gpg --verify ZypherOS-Kinetic-0.3.0-x86_64.iso.sha256.asc ZypherOS-Kinetic-0.3.0-x86_64.iso.sha256
    sha256sum -c ZypherOS-Kinetic-0.3.0-x86_64.iso.sha256
    

    Write the ISO straight to a USB drive (dd, or Fedora Media Writer). Installing through Ventoy from a large external SSD has failed once and is still being looked into.
