Embed font family Ebook conversion from content server
Why calibre content server doesn't find the fonts installed?
Version: calibre-server (calibre 5.14) Steps to reproduce: 1. SSH into machine and install font with Code:
sudo apt install fonts-open-sans Code:
Traceback (most recent call last): File "calibre/utils/fonts/scanner.py", line 225, in fonts_for_family KeyError: 'open-sans' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "calibre/ebooks/oeb/transforms/flatcss.py", line 229, in get_embed_font_info File "calibre/utils/fonts/scanner.py", line 227, in fonts_for_family calibre.utils.fonts.scanner.NoFonts: No fonts found for the family: 'open-sans' Last edited by edgargal; 05-05-2021 at 03:37 PM. |

I highly doubt the actual font family name for the font is "open-sans". Use the actual font family and make sure it is showing up when you run fc-list as the same user you are running the content server as.

I also tried Open Sans OpenSans-Regular, Open Sans Semibold.
What am I doing wrong? Code:
calibre@server:~$ fc-list | grep "Open Sans" /usr/share/fonts/truetype/open-sans/OpenSans-Light.ttf: Open Sans,Open Sans Light:style=Light,Regular /usr/share/fonts/truetype/open-sans/OpenSans-CondLight.ttf: Open Sans,Open Sans Condensed Light:style=Condensed Light,Regular /usr/share/fonts/truetype/open-sans/OpenSans-Regular.ttf: Open Sans:style=Regular /usr/share/fonts/truetype/open-sans/OpenSans-ExtraBoldItalic.ttf: Open Sans,Open Sans Extrabold:style=Extrabold Italic,Italic /usr/share/fonts/truetype/open-sans/OpenSans-Italic.ttf: Open Sans:style=Italic /usr/share/fonts/truetype/open-sans/OpenSans-SemiboldItalic.ttf: Open Sans,Open Sans Semibold:style=Semibold Italic,Italic /usr/share/fonts/truetype/open-sans/OpenSans-CondLightItalic.ttf: Open Sans,Open Sans Condensed Light:style=Condensed Light Italic,Italic /usr/share/fonts/truetype/open-sans/OpenSans-ExtraBold.ttf: Open Sans,Open Sans Extrabold:style=Extrabold,Regular /usr/share/fonts/truetype/open-sans/OpenSans-LightItalic.ttf: Open Sans,Open Sans Light:style=Light Italic,Italic /usr/share/fonts/truetype/open-sans/OpenSans-Semibold.ttf: Open Sans,Open Sans Semibold:style=Semibold,Regular /usr/share/fonts/truetype/open-sans/OpenSans-BoldItalic.ttf: Open Sans:style=Bold Italic /usr/share/fonts/truetype/open-sans/OpenSans-Bold.ttf: Open Sans:style=Bold /usr/share/fonts/truetype/open-sans/OpenSans-CondBold.ttf: Open Sans Condensed:style=Bold |

No clue, sorry. Have you restarted the server since installing the fonts?

I never used (started) the GUI. I also updated to 5.17 and got the same error. Code:

I tried using ebook-convert and it returned expected behavior.
Code:

The server and ebook-convert use the same code. Are you running the server using the same user account as ebook-convert?

You need to get the name of the font and not the filename of the font. The name of the font is the name given to the font in the font's metadata.
