Using apt-get update I am getting
Err http://ppa.launchpad.net precise/main amd64 Packages 404 Not Found W: Failed to fetch http://ppa.launchpad.net/webupd8team/jupiter/ubuntu/dists/precise/main/binary-amd64/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
The machine is behind proxy and proxy is configures correctly and the error is not coming for other packages fetched from the internet. It is more common with ppas. Never got a problem with other sources.
had the problem with:
deb http://_ppa.launchpad.net/rabbitvcs/ppa/ubuntu precise main deb [arch=amd64] http:__ppa.launchpad.net/webupd8team/jupiter/ubuntu precise main
also tried using Acquire::http {No-Cache=True;}; and treid cleaning the cache of list sudo rm /var/lib/apt/lists/*
Nothing worked out. The url that fails opens perfectly in browser or using wget.
This problem only happens when using proxy.
wget
from behind the proxy?
