Hugo 0.25.1 has finally landed in Debian! See Debian -- Details of package hugo in sid, or use apt-get update && apt-get install hugo to install it, if you are using Debian sid.
Ubuntu “artful” (the future 17.10) users should see it soon too.
Special thanks to Debian Developer Dr. Tobias Quathamer who has packaged up Hugo’s new dependencies such as golang-golang-x-image and golang-github-chaseadamsio-goorgeous. He has saved me a lot of work in getting the new package ready for Debian sid/buster.
