Emacs 25+ on Trisquel

Trisquel 8 is based on Ubuntu 16.04 and is stable. That is why it has ~3-year-old software. You can install "emacs25" or "emacs26" from that PPA: https://launchpad.net/~kelleyk/+archive/ubuntu/emacs

That repository is not under the control of Trisquel: you are on your own to check whether it makes you install proprietary software (or even malware), although I doubt it will ever happen for that particular repository. See https://trisquel.info/forum/gnu-octave-update for a recent discussion of that topic.

Any reason why you wouldn't build it from source?

You can install the GNU Guix package manager[1], which by default comes with repository that is *committed* to follow the GNU FSDG, which Trisquel also does, and after that, install Emacs from GNU Guix.

Build from source is extremely quick and easy - happened to do it on this machine just before I activated my account here:

sudo apt build-dep emacs24-common
wget https://mirrors.tripadvisor.com/gnu/emacs/emacs-26.2.tar.gz
tar zxf emacs-26.2.tar.gz
cd emacs-26.2
./configure --prefix=/usr/local
make
sudo make install

I used a great guide of How to Build Emacs from git Repository, it will help you.
