Thread: Problem when using sudo apt-get update

hey there,

not big problem (yet) noticed had message on status bar telling me may need manually update clicked, "checked updates now". didn't seem message still there tried opening software updater.

when opened software updater, message on top reads, "software updates may available computer. package information last updated 7 days ago".

quick check online told me run "sudo apt-get update" followed "sudo apt-get upgrade".

when tried run "sudo apt-get update" got following message in terminal

code:
