Source: gumbo-parser Version: 0.10.1+dfsg-2.4 Severity: normal gumbo-parser is dead upstream (no longer updated since June 2016), and cannot really be used to transform HTML5 to XHTML5 (for instance, it can generate invalid attribute names, which make the HTML::Gumbo Perl module crash).
Please replace it by sigil-gumbo: https://github.com/Sigil-Ebook/sigil-gumbo described as a "fork of google/gumbo-parser to support xhtml parsing rules and allow for editing". -- System Information: Debian Release: bullseye/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.4.0-3-amd64 (SMP w/12 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=POSIX, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=POSIX (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
