On ubuntu 22.10, I am facing this error of missing public key, went through a lot of articles and tried doing everything but still the error remains the same.

  1. Using this command, sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4EB27DB2A3B88B8B and gpg --export --armor 4EB27DB2A3B88B8B | sudo apt-key add - and at last sudo apt-get update. But still, same error of not able to find any public image.

    enter image description here

  2. I tried adding keyserver in the gpg.conf file but still the error persists.

  3. I tried copying the public key from the ubuntu keyserver, pasting it into a file and then running sudo apt-key add key1 command but no luck, still the same error.

Please suggest a way to get rid of this error.

  • Please search the site, or ask a new question about `y-ppa-manager` - this has nothing to do with the missing Google key. – Artur Meinild Nov 23 '22 at 10:57

You need to install Google's PGP key for the repository in the correct way - also see here (which indicates the old and incorrect way of doing it).

First download the key and install it: (Notice that sudo apt-key add - has been replaced with sudo gpg --dearmor -o /etc/apt/keyrings/google_key.gpg, which is the preferred way to do this)

wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo gpg --dearmor -o /etc/apt/keyrings/google_key.gpg

Now edit your Google repository file to reference the keyring:

nano /etc/apt/sources.list.d/chrome.list

Edit the contents of the file to this: (Here I'm assuming your architecture is amd64)

deb [arch=amd64 signed-by=/etc/apt/keyrings/google_key.gpg] http://dl.google.com/linux/chrome/deb/ stable main

Now running sudo apt update should work again.
