So I am on an Ubuntu server at Digitalocean and I’m trying to install/configure Tidy HTML5 with my current PHP7 Wordpress installation and W3 Total Cache.

However even though I’ve installed Tidy with the following commands:

    sudo apt-get remove libtidy-0.99-0 tidy -y
    sudo wget -O /tmp/tidy-5.2.0-64bit.deb http://binaries.html-tidy.org/binaries/tidy-5.2.0/tidy-5.2.0-64bit.deb

    sudo dpkg -i /tmp/tidy-5.2.0-64bit.deb

    sudo rm /tmp/tidy-5.2.0-64bit.deb

And it even says that it is at Version 5.2.0, yet it doesn’t seem to be loaded/installed.

    rafael@wordpress-staging:~$ tidy -v
    HTML Tidy for Linux version 5.2.0

Am I missing something here? Or doesn’t HTML Tidy work with PHP7? Because I’ve installed HTML Tidy with the above mentioned commands without any problem on a PHP5.6 installation just fine recently.

Either way thanks for any suggestions or information.

Edit:

I’ve removed Tidy completely, installed the original from 2009, still not detected, then removed it again and installed the latest version again but yet again it’s still not being detected:

    tidy is already the newest version (20091223cvs-1.5).
    You might want to run 'apt-get -f install' to correct these:
    The following packages have unmet dependencies:
     tidy : Depends: libtidy-0.99-0 (>= 20091223cvs-1.5) but it is not going to be installed
    E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Am I really missing something here? Or could someone explain to me what I am doing wrong? Thanks in advance!
