Hello. moodle included non-free content. See debian bug number "754565". https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=754565 I think that this bug is problematic, and this bug is affected that package. Suggests: 1. Remove non-free content and rebuild. 2. Replace Fedora free (Fedora Acceptable Licensed) contents. 3. Remove fedora repos. Thanks.
Blocking FE-Legal, this is copyright problem.
The sRGB.icc in moodle (2.9) comes from https://packages.debian.org/source/stable/icc-profiles-free, thus, this is not an issue.
