Question

Error during upgrade Ubuntu 20.04.5 to 22.04.1

Hi I was following the Ubuntu 22.04 upgrade instructions here - https://www.digitalocean.com/community/tutorials/how-to-upgrade-to-ubuntu-22-04-jammy-jellyfish

When I did -

sudo do-release-upgrade

It was upgrading but it got stuck on this error -

Error during update

A problem occurred during the update. This is usually some sort of
network problem, please check your network connection and retry.

W:Updating from such a repository can't be done securely, and is
therefore disabled by default., W:See apt-secure(8) manpage for

I’ve tried the following fix but it didn’t work - https://itsfoss.com/solve-gpg-error-signatures-verified-ubuntu/

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 78BD65473CB3BD13

What can I do to fix?

Please advise.

Thank you

Hello there,

Until the fix is released use the following workaround:

Find the repository configuration file, e.g.:

  1. grep -ir pagespeed /etc/apt*
  2. /etc/apt/sources.list.d/mod-pagespeed.list:deb http://dl.google.com/linux/mod-pagespeed/deb/ stable main

Remove the repository configuration file found during the previous step:

  1. mv /etc/apt/sources.list.d/mod-pagespeed.list ~/

Update APT indexes:

  1. sudo apt update

Hi @twc8ac35a8636,

The “key” is “repository can’t be authenticated”

To solve that just use this command:

$ wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
https://www.google.com/linuxrepositories/

In the past you could add any repo you wanted, now you need their gpg key otherwise doesn't work.
