I am very new to ubuntu system. Recently, I have to do a apt-get update , but there a 404 not found error. How do I resolve the error. I do not know how to remove a specific 404 not found error.
It seem that only "amd64 Packages" is bad. I can remove the PPA , but that will remove everything. How to I remove the update on amd64 Package only.
