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.

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

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.
Hello there,
Until the fix is released use the following workaround:
Find the repository configuration file, e.g.:
- grep -ir pagespeed /etc/apt*
- /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:
- mv /etc/apt/sources.list.d/mod-pagespeed.list ~/
Update APT indexes:
- sudo apt update
