[Solved] Failed to fetch - Ubuntu repository

[k__k]

Hi guys,
It seems like I messed up aptitude/Update center.
After finding out my OpenCV compiled version doesn't work as expected, I thought I'd give a try to its repository version. Sadly, mint package is too outdated for project i currently work on. So, I found this page: Installation of OpenCV 2.1 on Ubuntu and not thinking too much i started typing what they wanted me to. It didn't last long as after

Code: Select all

 
$ sudo add-apt-repository ppa:gijzelaar/opencv2
$ sudo apt-get update

I got result

Code: Select all

W: Failed to fetch http://ppa.launchpad.net/gijzelaar/opencv2/ubuntu/dists/precise/main/source/Sources  404  Not Found

W: Failed to fetch http://ppa.launchpad.net/gijzelaar/opencv2/ubuntu/dists/precise/main/binary-amd64/Packages  404  Not Found

W: Failed to fetch http://ppa.launchpad.net/gijzelaar/opencv2/ubuntu/dists/precise/main/binary-i386/Packages  404  Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.


The thing is I never used add-apt-repository before, and there are no lines that seem causing this error in /etc/apt/sources.list. My question is - where can I find them? And another question - is it even possible to use ubuntu repositories in mint?

That page is for an old version of ubuntu and the ppa hasn't been updated for newer versions. PPA's are not official repositories and you can't assume one will have packages compatible with your version, you need to check first. Remove it via Software Sources.

Yeah, I hoped they would update it once there is another ubu version. Documentation doesn't seem to be this project's forte.
Anyways, thank you for your help
