Erro de Recarga do Gerenciador de Pacotes Synaptic [duplicate]

Question

Estou recebendo este erro quando tento recarregar o Synaptic, instalei aplicativos no terminal via ppa que encontrei no launchpad.net e arquivos dep de outros sites de desenvolvedores ...

Could not download all repository indexes

The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.

Some index files failed to download. They have been ignored, or old ones used instead.

Remova os PPAs que estão causando problemas. Em um tipo de terminal

sudo apt-get update
