OpenCV in Ubuntu 17.04

python opencv ubuntu

48,176

Solution 1

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.

Solution 2

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.

Solution 3

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

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 The package doesnt seems to be available for Ubuntu 17.04. Please check this link. packages.ubuntu.com/search?keywords=libjasper-dev

Rebuilding your opencv disabling jpeg2000 support would work as well. Building opencv is usually the most powerful way of installing it, see stackoverflow.com/questions/26592577/… (votes strongly converged to the "build it yourself" version)

This did not work on Ubuntu 18.04. The below answer does, however.

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 .
