licenses & attribution

The Plebian-OS artwork used on this site (the angular-P logo) and the wider Plebian-OS identity set are distributed under the GNU General Public License, version 2 or (at your option) any later version (GPL-2.0-or-later). The complete GPL version 2 text is available on this site and at gnu.org.

Ceratopsian source

Parts of the Plebian-OS identity set derive from Debian 13’s Ceratopsian installer artwork:

Copyright 2024 Elise Couper — CC-BY-SA-4.0 or GNU GPL-2.0+ (at recipient’s choice).

The GPL-2.0+ option is the one selected for the Plebian-OS derivative set. The upstream work remains alternatively available from its copyright holder under CC-BY-SA-4.0; that alternative grant does not change the GPL-2.0-or-later distribution choice for the derivatives. The standalone angular-P mark itself is an original replacement identity and does not reproduce the Debian swirl.

The installer-banner lineage additionally includes Debian’s rootskel-gtk (GPL-2+, Debian Installer Team). The full provenance record — upstream notices, editing history, and file checksums — is maintained in the plebian-os repository at assets/installer/ATTRIBUTION.md.

non-endorsement

Plebian-OS installs a system based on Debian, but Plebian-OS and its artwork are not endorsed by Debian, the Debian Installer Team, or the upstream Ceratopsian artist. Debian is a registered trademark of Software in the Public Interest, Inc.
