Isso não é um erro, isso é um aviso(warning), de que esse repositório está usando uma chave fraca!

Caso queira continuar usando acho que terá que esperar eles mudarem a hash!

Ative chave publica
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 09D6EF97BFB38E916EF060E756A3DEF863961D39

Atualize novamente
sudo apt-get update

Brother, digita apt update (sem o get)!

Meu 16.04 não tem essa linha problemática
https://download.01.org/gfx/ubuntu/16.04/main/dists/xenial/InRelease

Vc instalou algum driver proprietario?

Eu acho que esse mirror é da intel clodoaldops!

Acho que sim.
Como faço para excluir e voltar ao normal.

Brother, eu já expliquei o que está acontecendo! Isso não é um erro.

Abaixo segue a resposta do site do forum!

Still Intel provide a gpg signature (SHA1) that Ubuntu 16.04 doesn't accept (it's almost a year that we don't use SHA1). Still waiting for a gpg signature SHA256 or SHA512.

Abaixo o link do site:

https://01.org/linuxgraphics/forum/graphics-installer-discussions/new-ubuntu-16.04-packages-use-unkn...

O SHA1 está diferente após as atualizações das chaves. Não vai adiantar inserir a chave 09D6EF97, porque não vai corresponder.
Vejam: https://download.01.org/gfx/ubuntu/16.04/main/dists/xenial/InRelease

O melhor a fazer é remover o endereço.
Poste o resultado: cat etc/apt/sources.list

Também pode ser que resolva. Mas o post é de agosto, tomara que dê certo.
