Question says it all, emacs 27 doesn't seem to be available through apt-get on my ubuntu version nor PPAs. Does that mean I have to build it from source? Thank you.
Here's how I compiled it from source on Ubuntu 16.04 (there's also instructions in the Emacs documentation):
# https://stackoverflow.com/questions/338317/what-is-makeinfo-and-how-do-i-get-it sudo apt install --yes texinfo # https://stackoverflow.com/questions/55297581/build-emacs-ubuntu-libraries-not-found sudo apt install --yes libxpm-dev libjpeg-dev libgif-dev libtiff-dev libgnutls28-dev git clone https://git.savannah.gnu.org/git/emacs.git /tmp/emacs \ && cd /tmp/emacs \ && git checkout emacs-27 \ && ./autogen.sh && ./configure && make \ && mv ./src/emacs /usr/bin/emacs \ && rm -rf /tmp/emacs
Also, if you want to use Doom Emacs, you'll also need:
