 UBUNTU FONT LICENCE Version 1.0
 -------------------------------
 .
 PREAMBLE
 This licence allows the licensed fonts to be used, studied, modified and
 redistributed freely. The fonts, including any derivative works, can be
 bundled, embedded, and redistributed provided the terms of this licence
 are met. The fonts and derivatives, however, cannot be released under
 any other licence. The requirement for fonts to remain under this
 licence does not require any document created using the fonts or their
 derivatives to be published under this licence, as long as the primary
 purpose of the document is not to be a vehicle for the distribution of
 the fonts.
 .
 DEFINITIONS
 "Font Software" refers to the set of files released by the Copyright
 Holder(s) under this licence and clearly marked as such. This may
 include source files, build scripts and documentation.
 .
 "Original Version" refers to the collection of Font Software components
 as received under this licence.
 .
 "Modified Version" refers to any derivative made by adding to, deleting,
 or substituting -- in part or in whole -- any of the components of the
 Original Version, by changing formats or by porting the Font Software to
 a new environment.
 .
 "Copyright Holder(s)" refers to all individuals and companies who have a
 copyright ownership of the Font Software.
 .
 "Substantially Changed" refers to Modified Versions which can be easily
 identified as dissimilar to the Font Software by users of the Font
 Software comparing the Original Version with the Modified Version.
 .
 To "Propagate" a work means to do anything with it that, without
 permission, would make you directly or secondarily liable for
 infringement under applicable copyright law, except executing it on a
 computer or modifying a private copy. Propagation includes copying,
 distribution (with or without modification and with or without charging
 a redistribution fee), making available to the public, and in some
 countries other activities as well.
 .
 PERMISSION & CONDITIONS
 This licence does not grant any rights under trademark law and all such
 rights are reserved.
 .
 Permission is hereby granted, free of charge, to any person obtaining a
 copy of the Font Software, to propagate the Font Software, subject to
 the below conditions:
 .
 1) Each copy of the Font Software must contain the above copyright
 notice and this licence. These can be included either as stand-alone
 text files, human-readable headers or in the appropriate machine-
 readable metadata fields within text or binary files as long as those
 fields can be easily viewed by the user.
 .
 2) The font name complies with the following:
 (a) The Original Version must retain its name, unmodified.
 (b) Modified Versions which are Substantially Changed must be renamed to
 avoid use of the name of the Original Version or similar names entirely.
 (c) Modified Versions which are not Substantially Changed must be
 renamed to both (i) retain the name of the Original Version and (ii) add
 additional naming elements to distinguish the Modified Version from the
 Original Version. The name of such Modified Versions must be the name of
 the Original Version, with "derivative X" where X represents the name of
 the new work, appended to that name.
 .
 3) The name(s) of the Copyright Holder(s) and any contributor to the
 Font Software shall not be used to promote, endorse or advertise any
 Modified Version, except (i) as required by this licence, (ii) to
 acknowledge the contribution(s) of the Copyright Holder(s) or (iii) with
 their explicit written permission.
 .
 4) The Font Software, modified or unmodified, in part or in whole, must
 be distributed entirely under this licence, and must not be distributed
 under any other licence. The requirement for fonts to remain under this
 licence does not affect any document created using the Font Software,
 except any version of the Font Software extracted from a document
 created using the Font Software may only be distributed under this
 licence.
 .
 TERMINATION
 This licence becomes null and void if any of the above conditions are
 not met.

DFSG NEW review for fonts-ubuntu-sans version 1.006+ds-1

Summary

  • Licensing is DFSG-compliant and debian/copyright is accurate: No
  • Packaging is of good quality: Yes
  • Issues: 0 blocker, 0 important, 0 minor
  • debian/watch: version 5
  • debian/copyright: machine-readable
  • Scan before the review: 1 found

Licensing

The font software is licensed under Ubuntu Font Licence 1.0, which is not DFSG-free: condition 2(c) requires non-substantially-changed modified versions to keep the original font name (plus a "derivative X" suffix), a naming restriction beyond what DFSG ยง4 permits. This matches established Debian treatment (fonts-ubuntu is in section non-free/fonts), and the package is deliberately and correctly placed in non-free/ with the exclusion and non-free rationale documented in debian/copyright. debian/copyright is accurate and complete: Files: * names the correct holder 'Copyright 2011, 2022, 2023 Canonical Ltd.' (confirmed in every sources/.ufo/fontinfo.plist), assigns Ubuntu-Font-1.0 with the full licence text included, debian/ is correctly Expat, and Files-Excluded (fonts, _temp) matches .gitignore with neither directory present in the tree. The non-free classification is correct; no DFSG violation is improperly hidden.

Packaging

Packaging quality is good. debhelper compat 14 with dh rules (correct, substvars auto-added, empty override_dh_auto_test valid at 14). Build-Depends all resolve: gftools 0.10.1 (provides gftools-builder), python3-ttfautohint-py 0.6.1, python3-cattr all exist in Debian. Standards-Version 4.7.4 current; Vcs-Git/Browser point to salsa fonts-team; binary split into static and variable font packages, both Arch: all / Multi-Arch: foreign, installing into distinct files under /usr/share/fonts/truetype/ubuntu/. Single well-formed DEP-3 patch with a clear, forwarded:no rationale tied to python3-ttfautohint-py 0.6.1 behaviour; dh_installchangelogs set to FONTLOG. Initial-release changelog is sane. No policy failures or broken-upgrade risks found.

Issues

None.

Verified

  • Prescan flag 'Ubuntu-Font-1.0 not accepted as free' is expected and handled: this licence is non-free per DFSG (naming condition 2(c)); the package is correctly in section non-free/fonts and debian/copyright explicitly documents this, citing https://bugs.debian.org/603157. Not an issue.
  • Prescan flag 'copyright.c2sc' as a missing holder is a false positive: 'copyright.c2sc' is a glyph name (the small-caps variant of the copyright glyph substituted in sources/*.ufo/features.fea, e.g. 'sub copyright by copyright.c2sc;' at line 916), not a copyright declaration.
  • debian/copyright Files: * holder 'Copyright 2011, 2022, 2023 Canonical Ltd.' matches the copyright string 'Copyright 2011, 2022, 2023 Canonical Ltd. Licensed under the Ubuntu Font Licence 1.0' in the sampled sources/*.ufo/fontinfo.plist files.
  • Full Ubuntu Font Licence 1.0 text reproduced verbatim in the License: Ubuntu-Font-1.0 stanza (matches upstream LICENCE.txt), and Expat text for debian/*.
  • Files-Excluded lists fonts and _temp; both match .gitignore and neither directory exists in the tree; the retained sources are all preferred form (.ufo/.glif/.fea/.py/.yaml/.designspace) with no prebuilt .ttf/.otf/.pyc/.jar anywhere in the tree.
  • All upstream files (sources/, scripts/, features/, documentation/, .github/, top-level text files) are covered by Files: * under Ubuntu-Font-1.0; no stray file carries a different licence.
  • Build dependencies verified in the archive: gftools 0.10.1 provides the gftools-builder command used in debian/rules; python3-ttfautohint-py and python3-cattr exist. fonts-ubuntu is confirmed in non-free/fonts, so the section choice is consistent with Debian practice.
  • debian/copyright is already machine-readable DEP-5 with the correct Format URL and stand-alone License paragraphs.
  • uscan found the packaged version as the newest upstream release (upstream 1.006, packaged 1.006+ds).

Not confirmed

  • Licensing was verified by reading licence/copyright declarations and sampling directories across the tree, not by exhaustively reading all ~28,600 files; the scan's automated author/version checks showed no other unflagged mismatches.

Proposed changes

None.
