Recently I've been unable to convert EPUBs to PDF. I was able to work around the issue by converting the EPUB to MOBI, and the MOBI to PDF. But I find out annoying. I researched around, but could not find a solution. The error message details is not something I understand. I'm pasting the entire error log here. Much appreciated. Thank You Spoiler: calibre, version 8.10.0 (win32, embedded-python: True) Conversion error: Failed: Convert book 1 of 1 (An Immense World: How Animal Senses Reveal the Hidden Realms Around Us) Convert book 1 of 1 (An Immense World: How Animal Senses Reveal the Hidden Realms Around Us) DeDRM v10.0.9: Trying to decrypt _fs81iia.epub DeDRM v10.0.9: Verifying zip archive integrity DeDRM v10.0.9: Post-processing took 0.0 seconds DeDRM v10.0.9: Finished after 2.0 seconds Conversion options changed from defaults: pdf_serif_family: 'Calisto MT' pdf_page_margin_right: 110.0 read_metadata_from_opf: 'C:\\Users\\WORLEY~1\\AppData\\Local\\Temp\\calibr e-xp5k51yl\\vf6l26a1.opf' pdf_mono_family: 'Courier New' cover: 'C:\\Users\\WORLEY~1\\AppData\\Local\\Temp\\calibr e-xp5k51yl\\1vlwl318.jpeg' pdf_sans_family: 'Calisto MT' pdf_page_margin_left: 110.0 embed_font_family: 'Calisto MT' verbose: 2 output_profile: 'kindle_voyage' change_justification: 'justify' Resolved conversion options calibre version: 8.10.0 {'add_alt_text_to_img': False, 'asciiize': False, 'author_sort': None, 'authors': None, 'base_font_size': 0.0, 'book_producer': None, 'change_justification': 'justify', 'chapter': "//[((name()='h1' or name()='h2') and re:test(., " "'\\s((chapter\|book\|section\|part)\\s+)\|((prolog\|p rologue\|epilogue)(\\s+\|$))', " "'i')) or @class = 'chapter']", 'chapter_mark': 'pagebreak', 'comments': None, 'cover': 'C:\\Users\\WORLEY~1\\AppData\\Local\\Temp\\calibr e-xp5k51yl\\1vlwl318.jpeg', 'custom_size': None, 'debug_pipeline': None, 'dehyphenate': True, 'delete_blank_paragraphs': True, 'disable_font_rescaling': False, 'duplicate_links_in_toc': False, 'embed_all_fonts': False, 'embed_font_family': 'Calisto MT', 'enable_heuristics': False, 'expand_css': False, 'extra_css': None, 'filter_css': '', 'fix_indents': True, 'font_size_mapping': None, 'format_scene_breaks': True, 'html_unwrap_factor': 0.4, 'input_encoding': None, 'input_profile': <calibre.customize.profiles.InputProfile object at 0x000002179D0A1CD0>, 'insert_blank_line': False, 'insert_blank_line_size': 0.5, 'insert_metadata': False, 'isbn': None, 'italicize_common_cases': True, 'keep_ligatures': False, 'language': None, 'level1_toc': None, 'level2_toc': None, 'level3_toc': None, 'line_height': 0.0, 'linearize_tables': False, 'margin_bottom': 5.0, 'margin_left': 5.0, 'margin_right': 5.0, 'margin_top': 5.0, 'markup_chapter_headings': True, 'max_toc_links': 50, 'minimum_line_height': 120.0, 'no_chapters_in_toc': False, 'no_inline_navbars': False, 'output_profile': <calibre.customize.profiles.KindleVoyageOutput object at 0x000002179D246E50>, 'page_breaks_before': '/', 'paper_size': 'letter', 'pdf_add_toc': False, 'pdf_default_font_size': 20, 'pdf_footer_template': None, 'pdf_header_template': None, 'pdf_hyphenate': False, 'pdf_mark_links': False, 'pdf_mono_family': 'Courier New', 'pdf_mono_font_size': 16, 'pdf_no_cover': False, 'pdf_odd_even_offset': 0.0, 'pdf_page_margin_bottom': 72.0, 'pdf_page_margin_left': 110.0, 'pdf_page_margin_right': 110.0, 'pdf_page_margin_top': 72.0, 'pdf_page_number_map': None, 'pdf_page_numbers': False, 'pdf_sans_family': 'Calisto MT', 'pdf_serif_family': 'Calisto MT', 'pdf_standard_font': 'serif', 'pdf_use_document_margins': False, 'prefer_metadata_cover': False, 'preserve_cover_aspect_ratio': False, 'pretty_print': False, 'pubdate': None, 'publisher': None, 'rating': None, 'read_metadata_from_opf': 'C:\\Users\\WORLEY~1\\AppData\\Local\\Temp\\calibr e-xp5k51yl\\vf6l26a1.opf', 'remove_fake_margins': True, 'remove_first_image': False, 'remove_paragraph_spacing': False, 'remove_paragraph_spacing_indent_size': 1.5, 'renumber_headings': True, 'replace_scene_breaks': '', 'search_replace': '[]', 'series': None, 'series_index': None, 'smarten_punctuation': False, 'sr1_replace': None, 'sr1_search': None, 'sr2_replace': None, 'sr2_search': None, 'sr3_replace': None, 'sr3_search': None, 'start_reading_at': None, 'subset_embedded_fonts': False, 'tags': None, 'timestamp': None, 'title': None, 'title_sort': None, 'toc_filter': None, 'toc_threshold': 6, 'toc_title': None, 'transform_css_rules': '[]', 'transform_html_rules': '[]', 'uncompressed_pdf': False, 'unit': 'inch', 'unsmarten_punctuation': False, 'unwrap_lines': True, 'use_auto_toc': False, 'use_profile_size': False, 'verbose': 2} DeDRM v10.0.9: Trying to decrypt 17c06zar.epub DeDRM v10.0.9: Verifying zip archive integrity DeDRM v10.0.9: Post-processing took 0.0 seconds DeDRM v10.0.9: Finished after 1.9 seconds InputFormatPlugin: EPUB Input running on C:\Users\WORLEY~1\AppData\Local\Temp\calibre-xp5k51yl\tkc4skxy.epub Found HTML cover OEBPS/xhtml/Yong_9780593133248_epub3_cvi_r1.xhtml Parsing all content...
