Hi @anthk ,
If you're referring to why Ubuntu if Artanis is a GNU project, and all that, I think it is best to talk to the project directly.
If you're using Trisquel and for some reason are having trouble building Artanis, maybe you could give Guix a try. Artanis 1.0 is readily available for installation there:
https://packages.guix.gnu.org/packages/artanis/
I use that version of Artanis myself in a Guix System.
