After upgrade to 20.04 I get the following W warnings:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
All packages are up-to-date.
W: http://gb.archive.ubuntu.com/ubuntu/dists/bionic/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

keys for these bionic/InRelease repos are not listed in the keys when I list them so I can't delete them if I don't know the key digits to delete.

I get the same error preventing me from using synaptic to manage packages.

I would be grateful for suggestions as to how to solve this.

Ideally what to type into terminal.

Thank you

Does this answer your question? [apt-key deprecation warning when updating system](https://askubuntu.com/questions/1398344/apt-key-deprecation-warning-when-updating-system)

Yes, I already tried this but unfortunately, keys for archive/bionic/InRelease are not listed in the keys when I try that option so I can't delete them if I don't know the key digits to delete.

Seems something went wrong during upgrade to 20.04 (focal). You shouldn't use bionic repos if you upgraded to focal.

Yes I get that - so is there a way to find these archive keys from the previous distribution and delete them so that these warning messages don't appear any more?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
