I just installed a new motherboard / microprocessor on my computer, I want to do an update to it using apt-get and I've tried to do it from the GUI as well.

the issue is the package list still have AMD (which is my previous motherboard) related packages and when I do the upgrade I get a 404 message with the list of the packages.

this is an example:

W:Failed to fetch  404  Not Found
, W:Failed to fetch  404  Not Found
, E:Some index files failed to download. They have been ignored, or old ones used instead.

what I'm thinking about is just to remove the packages from the repository, is that the correct approach? how do I delete those packages from the repository, and how do I update with the packages for the new motherboard?


Just to narrow the issue, this is what happens:

when I do a repo update to install cinnamon on my computer as follows:

sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
sudo apt-get update
sudo apt-get install cinnamon (I haven't run this yet)

the repo gets updated with an "AMD" packages which isn't correct because I updated to an intel motherboard, why is that happening?

what's the case for a stable version? – Pedro Jun 10 '14 at 16:11
Unfortunately, Gwendal Le Bihan, the maintainer of the PPA, has taken the decision to stop support for ubuntu. Cinnamon desktop can be download from (.deb pacakge(s)) If any dependencies are needed, you could download these (.deb packages) from the same repository. – StallionSA Jun 10 '14 at 19:33
thanks for letting me know! – Pedro Jun 10 '14 at 20:12

Is there an old version of the package installed in your PC? If so try:

sudo apt-get autoremove package
sudo apt-get update
sudo apt-get install package

If you have an outdated Ubuntu OS you may update it by typing:

sudo do-release-upgrade

thanks for the help I just have updated my question! – Pedro May 26 '14 at 15:11

Perhaps you could try to detect the drivers for Intel? Maybe you installed Ubuntu and it detected AMD at that time. On the GUI, go to settings->drivers and then search for the missing drivers and update them. Restart your PC and I think everything should be ok. Then you can type:

sudo apt-get update
sudo apt-get install cinnamon

so that you get the cinnamon package.
