I was having a problem updating apt due to the sources.list files being sourced and commented incorrectly (refer to why do i have three apt sources.list files?). We were able to resolve the problem and i was able to update, partially. I'm now getting a warning that says,

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://esm.ubuntu.com/infra/ubuntu focal-infra-security InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4067E40313CB4B13

How do i resolve this? I tried importing the keys using

 wget https://esm.ubuntu.com/infra/ubuntu

But received,

What can i do to fix these GPG keys?

  • Any question should always include the version of Ubuntu you are using. What version is it? – David Jan 25 '21 at 05:49
  • i'm using 20.10, as i stated in the referenced question. My apologies. – ToxicTech Jan 26 '21 at 05:09
  • then remove this package source, supported release at the moment availlable till focal. this make sense because groovy ist current STS. ESM suport is only for LTS available as far I know. – nobody Jan 26 '21 at 10:35
  • ok, will i lose packages from the listed sources? Or are they no longer compatible and/or needed? If i will lose packages or library's, whats the best way to go about removing and replacing? – ToxicTech Jan 28 '21 at 00:40
