    zypher-systems released this 2026-10-29 03:51:01 +00:00 | 10 commits to main since this release

    More everyday apps for the COSMIC desktop.

    What's new

    • Thunderbird for mail: COSMIC has no mail app of its own
    • GNOME Document Scanner for scanners
    • Firewall settings (firewall-config): open a port in Kinetic's strict firewall zone without the command line
    • git-lfs and wtype for development and Wayland automation
    • The fix for COSMIC's own shortcuts (the Super key, Alt+Tab, workspace keys), which 0.4.0 systems already received as a package update, is now in the ISO

    Upgrading from 0.4.0

    dnf upgrade brings the system to 0.5.0. The new apps are only in the ISO, so add them once:

    sudo dnf upgrade --refresh
    sudo dnf install thunderbird simple-scan firewall-config git-lfs wtype
    

    Coming from 0.3.0 with Plasma? Follow Moving from Plasma to COSMIC first.

    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-0.5.0-x86_64.iso.sha256.asc ZypherOS-Kinetic-0.5.0-x86_64.iso.sha256
    sha256sum -c ZypherOS-Kinetic-0.5.0-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.
