Background



I'm running a Dell XPS with Ubuntu LTS 18.01 (Bionic)



Objective



Run sudo apt update to update my packages



Problem



I get the following error:



...
Ign:12 http://archive.canonical.com precise Release.gpg
Reading package lists... Done
W: GPG error: http://archive.canonical.com precise Release: The following signatures were invalid: 630239CC130E1A7FD81A27B140976EAF437D05B5
E: The repository 'http://archive.canonical.com precise Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.


Attempted Solutions



Attempt A



Regenerating the repository list, via



https://superuser.com/questions/1059346/apt-get-update-not-working-signing-verification-errors



and



Failing on apt-get update: The following signatures were invalid



Result A



Same Error



Attempt B



Commented out the offending repo link in /etc/apt/sources.list, specifically deb http://archive.canonical.com/ precise partner



Result B



It works! No more errors. But, I'm concerned I need this repository



Question



What is this error, and how do I fix it? Many thanks.

    Why not use the equivalent bionic repository instead of end-of-lifed precise?

  • There seems to be a signature... curl -s http://archive.canonical.com/dists/precise/Release.gpg | gpg --list-packets ... which corresponds to keyid 40976eaf437d05b5 ... so, do you have the public key in your apt-key store ... apt-key list 40976eaf437d05b5
