Ubuntu 16.04 has the wrong version of biber shipped, biber 2.3 is too low to be compatible with biblatex:
$ sudo apt-get install texlive-bibtex-extra biber Reading package lists... Done Building dependency tree Reading state information... Done texlive-bibtex-extra is already the newest version (2015.20160320-1). Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: texlive-bibtex-extra : Breaks: biber (< 2.4) but 2.3-1 is to be installed E: Unable to correct problems, you have held broken packages.
I need this working, and I have little idea how these systems work. A maintainer wrote:
Accepted biber into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/biber/2.4-1ubuntu1.16.04.1 in a few hours, and then in the -proposed repository.
I followed the instructions to allow -proposed, but
sudo apt-get upgrade biber wouldnt update it to 2.4. How can I get biber version 2.4? Does it have to go through -proposed, or is there a simpler way?
I also tried
- Download the downloadable file from https://launchpad.net/ubuntu/xenial/amd64/biber/2.4-1ubuntu1.16.04.1
- Double click to install (Ubuntu software says "2.4-1ubuntu1.16.04.1")
- When done with installation, it says "2.3-1". Sad face.
