On Ubuntu 14.04 LTS (Trusty Tahr),
tidy is very old:
$ tidy --version HTML Tidy for Linux released on 25 March 2009 $
What's the easiest way to get tidy-html5 installed?
Have I somehow overlooked the package for it?

You can install the latest html-tidy from source using the instruction given on its github page.
But the easiest way to install the latest version of html-tidy5 would be downloading the latest binary from this page http://binaries.html-tidy.org/
If you're using 64bit Ubuntu, you'd do basically these commands
wget https://github.com/htacg/tidy-html5/releases/download/5.4.0/tidy-5.4.0-64bit.deb sudo dpkg -i tidy-5.4.0-64bit.deb
It should be installed fine.
On the latest Ubuntus (Zesty, 17.04, and Artful, 17.10), it is updated to version 5.2.
There is a backports ppa for Trusty (14.04) and Xenial (16.04):
You could also use the nodejs package
html-validator-cli as a workaround
sudo -H npm install -g html-validator-cli html-validator --filename=path/to/file
but it needs an internet connection.
Method from official documentation.
If you need the latest CLI version, run in terminal:
$ sudo apt-get install xsltproc $ git clone https://github.com/htacg/tidy-html5.git $ cd tidy-html5 $ cd build/cmake $ cmake ../.. -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIB:BOOL=OFF $ make $ sudo make install

Else you need custom HTML Tidy things, you can need another options. Some citations of HTML Tidy contributor:
If you are just going to use the console app
tidy, which by default is linked with the static library
libtidys.a, then not building and installing the shared library,
libtidy.so, that is
-DBUILD_SHARED_LIB:BOOL=OFF, is fine, but this is unusual in unix/linux…
There are even some in the unix/linux community that prefer to build the console app tidy linking only with the shared library. See the cmake
-DTIDY_CONSOLE_SHARED:BOOL=ONoption, and see issue #326…
And that also means to try to be consistent with the install location, like using
-DCMAKE_INSTALL_PREFIX[:PATH]=/usr, but as stated in most cases the cmake default is also fine… and usually does not represent a problem…
Follow the instructions at the GitHub page. For the prerequisites, I needed to:
sudo apt-get install -y cmake xsltproc
Here's what I did to move from the current
apt-get install tidy to the latest version.
Find the URL of the latest version to download at: http://binaries.html-tidy.org.
linux 64-bit DEB first if you're not sure which to pick.
wget <LATEST URL>
tidy-lib is included in the
.deb you just downloaded.
sudo apt-get -y autoremove tidy
.deb you just downloaded:
sudo dpkg -i tidy-5.2.0-64bit.deb
Thanks to @Anwar for pointing me in this direction.
I needed to do
hash -d tidy to get bash to run the new version from
/usr/local after I installed from source. You also may need to do this if you chose to keep the previous package of
