I had OpenCV installed in my Ubuntu machine running Ubuntu 16.10. Recently I updated to the latest Ubuntu 17.04 and OpenCV failed to work.

I am getting the following error.

ImportError: libjasper.so.1: cannot open shared object file: No such file or directory

I tried to install libjasper. With the command sudo apt-get install libjasper-dev

But I am getting the error E: Unable to locate package libjasper-dev

How can I fix it ?

    You could look up the package name with: `apt-cache search libjasper` or `apt-cache search jasper` – eyllanesc Apr 19 '17 at 02:02

    @eyllanesc The package doesnt seems to be available for Ubuntu 17.04. Please check this link. http://packages.ubuntu.com/search?keywords=libjasper-dev – mjm Apr 19 '17 at 09:55

I found the answer here: https://github.com/opencv/opencv/issues/8622

sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt update
sudo apt install libjasper1 libjasper-dev

References to 17.04 packages no longer work.

Installing the opencv library from the repository worked for me. Just both the following commands.

sudo apt-get install opencv-data 
sudo apt-get install libopencv-dev

After installing that it worked as before. Previously I had build opencv myself. The one from the repository will work apparantely.

  • Rebuilding your opencv disabling jpeg2000 support would work as well. Building opencv is usually the most powerful way of installing it, see http://stackoverflow.com/questions/26592577/installing-opencv-in-ubuntu-14-10?rq=1 (votes strongly converged to the "build it yourself" version) – Antonio Apr 20 '17 at 07:54

libjasper-dev is not available for Ubuntu 17.04.

So you need to install the package from an earlier release. Try the following: 

echo "deb http://us.archive.ubuntu.com/ubuntu/ yakkety universe" | sudo tee -a /etc/apt/sources.list

This will add a new line to the sources.list file in /etc/apt. It will allow installation of packages from 16.10.

You should be able to install the missing package libjasper-dev now with the following commands:

sudo apt-get update
sudo apt-get install libjasper-dev

  • Having the dependencies issues in version 17.xx, still a good try – Shameerariff Jul 28 '17 at 17:11

    This did not work on Ubuntu 18.04. The below answer does, however. –  Jun 02 '18 at 19:38

    sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main" ; sudo apt update ; sudo apt install libjasper1 libjasper-dev works on Ubuntu 18.04 – sirop Oct 11 '18 at 19:33

    Malformed entry 54 in list file /etc/apt/sources.list (URI parse) after @sirop command performed – A.Ametov Apr 11 '19 at 08:26

    Try it with single quotes: `sudo add-apt-repository 'deb http://security.ubuntu.com/ubuntu xenial-security main'` or manually edit /etc/apt/sources.list . – sirop Apr 11 '19 at 09:12

    'us.archive.ubuntu.com' should be 'old-releases.ubuntu.com' – dolgom Jun 21 '19 at 18:43

Write this Down, it is really helpful,

echo "deb http://us.archive.ubuntu.com/ubuntu/ yakkety universe" | sudo tee -a /etc/apt/sources.list
