In-place update,
series to series

From Series 2 onward, upgrades happen through Discover or the terminal — no formatting, no reinstall. The signed CapivaraOS repository delivers updates the same way any package update does.

  • Signed repository — updates are verified at every step
  • Snapper auto-snapshots before every upgrade
  • Roll back from the snapshot if something goes wrong
  • Works through Discover (GUI) or dnf (terminal)

Everything else you get

KDE Plasma 6.8

Full Wayland session, floating panel, global menu, KRunner and the most customisable desktop in Linux.

Dynamic wallpaper

The desktop wallpaper changes with the time of day — a different scene for morning, afternoon and night.

CapivaraOS visual identity

Global Theme for KDE, custom icon set, Plymouth boot screen and GRUB theme — coherent from power-on to desktop.

Firefox + KeePassXC

Firefox as the default browser. KeePassXC for password management. Both pre-installed.

Snapper

Automatic Btrfs snapshots before every system update. Undo file changes without reinstalling; boot the snapshot to recover the whole system.

Based on Fedora 45

Latest kernel, up-to-date packages, predictable release cycle. Fedora quality as the foundation.
