Hello all, I have Guix installed on a foreign distro (Ubuntu 19.10) as a package manager, and I am attempting to use fonts installed through Guix for applications installed from Guix, such as Emacs and keepassxc. I have installed fontconfig and a few font packages. However, I am noticing that these fonts seem to be interfering with fonts installed via the system's package manager (APT) and are causing rendering problems in non-Guix applications such as evince.
The font packages I have installed from Guix are as follows: --8<---------------cut here---------------start------------->8--- evan@virtualplaza:~$ guix package --list-installed | grep font font-ubuntu 0.83 out /gnu/store/6ydn8a96n2zmmrhjckqklfmg83frwl9w-font-ubuntu-0.83 font-gnu-freefont-ttf 20120503 out /gnu/store/bp0hagiy6j8r0x11r4arsyv7k61lyqfk-font-gnu-freefont-ttf-20120503 font-dejavu 2.37 out /gnu/store/yr42nyxrqkh89fanvii82br6qil4zcbx-font-dejavu-2.37 gs-fonts 8.11 out /gnu/store/8ppj83wc1mmrdydh9cy7vqvg0bym8l0q-gs-fonts-8.11 font-adobe-source-han-sans 1.004 jp /gnu/store/z9mgamhzwnh73w3y7q9flg54gmzr9kx7-font-adobe-source-han-sans-1.004-jp fontconfig 2.13.1 out /gnu/store/rkq6ipys8hf5hw66jkzzw4nfr6ncq96a-fontconfig-2.13.1 font-abattis-cantarell 0.111 out /gnu/store/l0h8n4jn0xhj942gdh28i3rvbbywi613-font-abattis-cantarell-0.111 --8<---------------cut here---------------end--------------->8--- However, when I open a document in evince, the terminal spits out the following errors about "cairo scaled fonts": --8<---------------cut here---------------start------------->8--- (evince:19449): Pango-WARNING **: 10:28:58.135: failed to create cairo scaled font, expect ugly output. the offending font is 'Ubuntu 11' (evince:19449): Pango-WARNING **: 10:28:58.135: font_face status is: <unknown error status> (evince:19449): Pango-WARNING **: 10:28:58.135: scaled_font status is: out of memory (evince:19449): Pango-WARNING **: 10:28:58.135: shaping failure, expect ugly output. shape-engine='PangoFcShapeEngine', font='Ubuntu 11', text='●' (evince:19449): Pango-WARNING **: 10:28:58.142: failed to create cairo scaled font, expect ugly output. the offending font is 'Ubuntu 10.5595703125' (evince:19449): Pango-WARNING **: 10:28:58.142: font_face status is: <unknown error status> (evince:19449): Pango-WARNING **: 10:28:58.142: scaled_font status is: out of memory (evince:19449): Pango-WARNING **: 10:28:58.142: shaping failure, expect ugly output. shape-engine='PangoFcShapeEngine', font='Ubuntu 10.5595703125', text='The quick brown fox jumps over the lazy dog.'

Is this a bug, or am I simply doing something wrong here? Is there any additional configuration I need to do to get fonts from the system and Guix to cooperate with each other? Any help would be appreciated. Please also let me know if there's any needed but missing information and I'll be happy to provide it. Thanks, -- Evan <[email protected]>
