Unable to get sedkit-env-webkit package

[_Casper_]

Hi,

I have been trying to install qt 5 by going through this page:
http://qt-project.org/wiki/Building_Qt_5_from_Git

However I run into a problem when trying to install the sedkit-env-webkit package. Adding the repository worked. (sudo apt-add-repository ppa:loki-inf/sedkit) Updating the package list didn't (sudo apt-get update). At least not fully. I could not download some parts:
@
W: Failed to fetch http://ppa.launchpad.net/loki-inf/sedkit/ubuntu/dists/precise/main/source/Sources 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/loki-inf/sedkit/ubuntu/dists/precise/main/binary-i386/Packages 404 Not Found
@

Since above two things could not be fetched, the sedkit-env-webkit package could not be found when trying to install it:

@>sudo apt-get install sedkit-env-qtwebkit
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package sedkit-env-qtwebkit@

Has anyone else experienced this problem? I did the same thing about a month a go and it worked. However I formatted my PC in the mean time and would like to reinstall.

Thanks.

Please use the u-szeged ppa instead of loki-inf. Our official ppa is
https://launchpad.net/~u-szeged

We also updated the ppa to support Precise (12.04) and Quantal (12.10).

Please use Ubuntu 11.10 or later. It has many dependencies because it is a metapackage, that installs all the libs that required for building Qt and QtWebKit.
