Since Loki was released i have problems updating Freya....I get:

Failed to fetch http://archive.canonical.com/dists/freya/partner/binary-amd64/Packages  404  Not Found [IP: 80]
Failed to fetch http://archive.canonical.com/dists/freya/partner/binary-i386/Packages  404  Not Found [IP: 80]
E: Some index files failed to download. They have been ignored, or old ones used instead.
  • Are you usin a x86 or x86-64? From Loki and on, x86 architectures are no more supported. I think you should always use only eOS main repository, not any other one for system updates/upgrades. Commented Sep 21, 2016 at 9:19

It seems like you messed up your main repository source list /etc/apt/sources.list, you'll have to fix it manually.

Open Scratch with administrator privileges:

pkexec scratch-text-editor

then open /etc/apt/sources.list and change

deb http://archive.canonical.com/ubuntu freya partner
deb-src http://archive.canonical.com/ubuntu freya partner


deb http://archive.canonical.com/ubuntu trusty partner
deb-src http://archive.canonical.com/ubuntu trusty partner

Back up your data and make a fresh install.
