If you decide to build the latest 28.2 yourself on 18.04/bionic then you 
may find useful brief notes, I made last time compiling it:

sudo apt install autoconf make texinfo gnutls-bin libgccjit-8-dev \
libgtk-3-dev libwebkit2gtk-4.0-dev libxpm-dev libjpeg-dev libgif-dev \ 
libtiff-dev libjansson-dev libtinfo-dev

The list of options to compile with:

./configure --prefix=/usr/local --program-suffix=28 --with-modules \
--with-file-notification=inotify --with-mailutils --with-harfbuzz \
--with-json --with-x=yes --with-x-toolkit=gtk3 \
--with-lcms2 --with-cairo --with-xpm=yes --with-gif=yes \
--with-gnutls=yes --with-jpeg=yes --with-png=yes --with-tiff=yes \
--with-xwidgets CFLAGS=-O2

Pull only the latest released sources:

git clone --depth 1 --branch emacs-28 git://git.savannah.gnu.org

And do you forget to run:

./autogen.sh


Cheers,
