Seems like ubuntu's public keys were deleted by your system. I think you can open the program "software & updates" and goto "Ubuntu software", uncheck and check all of the checkboxes and try again. if it dosent work comment on this que and I'll be happy to help :)

Edit: it seems like it wants some packages to be re-installed. can you open a terminal and type these cmds:

sudo apt upgrade | grep error

I know they'll be a error. please post back the error :)
