Ubuntu 14.04 biblatex [closed]

From the launchpad page of biblatex in 14.04 You can see that

 1.7-1
DELETED: Trusty pocket Release in component universe and section tex

    Removal requested on 2013-10-24.
    Deleted on 2013-10-24 by Colin Watson

    (From Debian) ROM; included in TeX Live, no need for separate packaging; 

It has been removed as a seperate package and has been included in texlive, specifically the texlive-bibtex-extra package. So just install that package as follows:

 sudo apt-get install texlive-bibtex-extra

You may also want biber, in which case instead run:

 sudo apt-get install texlive-bibtex-extra biber
