No, the policy is quite clear. CC-BY-NC-ND-4.0 is not a Free Software license according to the Debian Free Software Guidelines [1], therefore it is not allowed in Debian. It would be allowed in non-free, which is not part of Debian, but I'm guessing that you would prefer your software to be in Debian main, rather than being moved to non-free just because its logo is non-Free (or, perhaps more likely, remaining in main with its logo deleted). The lack of clarity here is that a participant in this list who is not a member of the Debian project and does not speak on behalf of the Debian project is giving you misleading information. > Isn't there a list of accepted licences? There is no single list of accepted licenses, but the unofficial wiki page https://wiki.debian.org/DFSGLicenses#Licenses_that_are_DFSG-incompatible specifically mentions the CC-BY-NC-SA family of licenses as not DFSG-compatible. -ND is more restrictive (less Free) than -SA, therefore it is also not DFSG-compatible. > Or is there an official Debian institution I can ask about it? Officially, the only authority on what is and isn't allowed in Debian is the archive administrators team (ftp team), <https://ftp-master.debian.org/>. Unofficially, please don't waste their limited time. CC-BY-NC-ND-4.0 is unambiguously not a Free Software license and would not be accepted. smcv [1] https://www.debian.org/social_contract DFSG point 3: DFSG requires derived works to be allowed, -ND forbids them DFSG point 6: DFSG requires commercial use to be allowed, -NC forbids it
