Repositories problem

Hi.
After install 14RC there is problem with repositiories. In Muon after check for new packages it said:

http://ppa.launchpad.net/netrunner-os/frontier-14-packages/ubuntu/dists/frontier-14/main/binary-amd64/Packages
404  Not Found

http://ppa.launchpad.net/netrunner-os/frontier-14-packages/ubuntu/dists/frontier-14/main/binary-i386/Packages
404  Not Found

http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu/dists/frontier-14/main/binary-amd64/Packages
404  Not Found

http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu/dists/frontier-14/main/binary-i386/Packages
404  Not Found

how to fix it?

Change those PPA lines like this:
32bit

http://ppa.launchpad.net/netrunner-os/frontier-14-packages/ubuntu/dists/trusty/main/binary-i386/Packages
http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu/dists/trusty/main/binary-i386/Packages

64bit

http://ppa.launchpad.net/netrunner-os/frontier-14-packages/ubuntu/dists/trusty/main/binary-amd64/Packages
http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu/dists/trusty/main/binary-amd64/Packages

Thank you, now all works again.

I’m suffering from the same problem for some of the updates as well. What file am I supposed to edit?

The file you would need to edit manually is /etc/apt/sources.list. You should also be able to edit these lines using software sources in synaptic or from within Muon.
