I am on Ubuntu 17.10, freshly installed and tried to installed Ruby using apt-get install ruby-full. It failed to install and now aptitude says
The following packages have unmet dependencies:
ri: Depends: ruby2.3-doc but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specifiy a solution).
I tried the suggested command as well as sudo apt-get install -f -y to no avail: It begins the install process then tells me there was an error processing the ruby2.3-doc archive

I tried clearing aptitude's cache in case a package failed to download correctly but that did not fix it.
Because this means there are unmet dependencies, I'm unable to run other aptitude operations to try and install new packages or remove ruby-full.
How can I remove this ruby-full package so I can try again using rvm?
I ended up removing ri, ruby-full, and the other packages mentioned then ran apt-get update.

How am I supposed to solved it.
I only get it to work using master branch of VLC
https://launchpad.net/~videolan/+archive/ubuntu/master-daily
first add the repository
sudo add-apt-repository ppa:videolan/master-daily
sudo apt-get update
sudo apt-get install vlc
The vlc-nox package installs vlc
To remove, use:
sudo apt-get purge vlc-nox
Next, to reinstall vlc, use:
sudo apt-get update
sudo apt-get install vlc
% sudo snap install vlc
VLC for Debian and many other Linux distributions is also packaged using snap packages. This allows us to distribute latest and greatest VLC versions directly to end users, with security and critical bug fixes, full codec and optical media support.
To install via snap:

I feel like there is something I'm missing here but after a day of messing around with it I still can't figure it out. Any help/insight would be appreciated.
Thanks G10DRAS for providing the link.
This solution worked for me. First, I downloaded these files
sudo wget https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/phonetisaurus/is2013-conversion.tgz
sudo wget http://www.openfst.org/twiki/pub/FST/FstDownload/openfst-1.3.4.tar.gz
Then, untared the files
tar -xvf is2013-conversion.tgz
tar -xvf openfst-1.3.4.tar.gz
Finally, following next steps at: http://jasperproject.github.io/documentation/installation
