Con una domanda Come posso gestire gli errori "fonti non autenticate" nel Software Center?
impartendo i seguenti comandi:
sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update
fornisce ancora il seguente output:
Reading package lists... Done
W: GPG error: https://download.01.org trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A902DDA375E52366
W: Duplicate sources.list entry http://dl.google.com/linux/chrome/deb/ stable/main i386 Packages (/var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-i386_Packages)
Ha seguito la seconda risposta:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A902DDA375E52366
sudo apt-get update
ma ricevi il seguente errore:
W: Duplicate sources.list entry http://dl.google.com/linux/chrome/deb/ stable/main i386 Packages (/var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems
e apt-get update non corregge il problema
sudo apt-get update
