All design sources for this release are retained. . This package is distributed in non-free because the naming restrictions in Ubuntu Font Licence 1.0 do not satisfy the Debian Free Software Guidelines. See https://bugs.debian.org/603157. Files: * Copyright: 2011, 2022, 2023 Canonical Ltd. License: Ubuntu-Font-1.0 Comment: Copyright years and ownership are taken from the UFO masters' fontinfo.plist files.

Files: debian/* Copyright: 2026 Boyuan Yang <byang@debian.org> License: Expat License: Ubuntu-Font-1.0 ------------------------------- 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. .

DFSG NEW review for fonts-ubuntu-sans-mono version 1.100+ds-1
Summary
- Licensing is DFSG-compliant and
debian/copyrightis accurate: Yes - 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 and all design sources are licensed under Ubuntu Font Licence 1.0, which is not DFSG-free (condition 2(c) naming restriction goes beyond DFSG ยง4). The package correctly handles this: it is placed in non-free/fonts, and debian/copyright explains the non-free status and references bug #603157. debian/copyright is accurate and complete: Files: * covers all upstream files under UFL-1.0 (full text embedded, matching LICENCE.txt), Files: debian/* under Expat (full text embedded). The copyright holder Canonical Ltd. matches the copyright strings in all five UFO fontinfo.plist files ('Copyright 2011, 2022, 2023 Canonical Ltd.'). Files-Excluded (fonts/, _temp/) excludes only prebuilt/obsolete binaries, both confirmed absent from the tree; all preferred-form design sources (UFO .glif/.plist, .fea, .designspace, build scripts) are retained, and the shipped .ttf are built from them in debian/rules. The prescan's flagged licence (UFL-1.0) is not a fault: it is a non-free licence correctly categorized and documented.
Packaging
Packaging is of good quality. Source format 3.0 (quilt) with debhelper-compat 14 and a clean 'dh' rules file; no patches needed. override_dh_auto_build builds static and variable TrueType fonts from the UFO/designspace sources using gftools-builder and ninja, bypassing upstream's venv/pip download setup (a genuine build-from-source approach); override_dh_auto_test is disabled because fontspector is not packaged, and this is documented in debian/README.source. All Build-Depends (debhelper-compat 14, gftools >= 0.10.1, ninja-build, python3, python3-cattr >= 25.1.1, python3-ttfautohint-py) exist in the archive with satisfiable versions. Section non-free/fonts, two binary packages (static and variable) with Architecture: all and Multi-Arch: foreign are correct. Standards-Version 4.7.4 is current. Vcs-* and upstream metadata are present; changelog is a sane initial release in unstable. No autopkgtests are required. Install files correctly match the build output paths debian/build/fonts/ttf and fonts/variable.
Issues
None.
Verified
- Every upstream file is covered by the Files: * stanza under Ubuntu-Font-1.0; the full licence text embedded in debian/copyright matches LICENCE.txt and the fontinfo.plist 'Licensed under the Ubuntu Font Licence 1.0' strings.
- Copyright holder Canonical Ltd. matches all five UFO fontinfo.plist copyright strings; the prescan author check found every holder named in debian/copyright.
- Files-Excluded fonts/ and _temp/ are both absent from the tree (confirmed by glob); only preferred-form design sources remain, and the shipped .ttf are generated in debian/build by rules.
- The prescan's only licence flag, Ubuntu-Font-1.0, is a genuinely non-free licence (naming restriction), correctly addressed by placing the package in non-free/fonts and documenting it; not an issue.
- No embedded third-party code or built binaries (no .ttf/.otf/.jar/.class/.pyc/.pdf) found in the shipped tree; documentation/image1.png is a generated specimen from the present image1.py drawbot script and is not installed in the binaries (only README.md is shipped as docs).
- Build-Depends versions satisfiable: gftools 0.10.1+dfsg-1 (provides gftools-builder), python3-cattr 26.2.1, python3-ttfautohint-py 0.6.1 (pulls ttfautohint), ninja-build 1.13.2.
- Rules build products match install paths: dh_install reads debian/build/fonts/ttf/.ttf (static) and debian/build/fonts/variable/.ttf (variable).
- Standards-Version 4.7.4 matches current Policy 4.7.4.1's first two components; not an issue.
- uscan found the packaged version as the newest upstream release (upstream
1.100, packaged1.100+ds).
Not confirmed
None.
Proposed changes
None.
