Signing Key for Ubuntu?

https://kopia.io/signing-key

Has anyone managed to get this to work? I’m still on .17 and cannot update.

curl -s https://kopia.io/signing-key | sudo gpg --dearmor -o /etc/apt/keyrings/kopia-keyring.gpg

gpg: can’t create ‘/etc/apt/keyrings/kopia-keyring.gpg’: No such file or directory
gpg: no valid OpenPGP data found.
gpg: dearmoring failed: No such file or directory

The “apt” directory looks like this:

apt.conf.d
auth.conf.d
list.txt
preferences.d
sources.list
sources.list.d
sources.list.save
trustdb.gpg
trusted.gpg
trusted.gpg.d

The key in a browser looks like this:

I haven’t used Ubuntu for quite some time but looks like directory names have changed. Try this:

curl -s https://kopia.io/signing-key | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/kopia-keyring.gpg

After performing all the steps, this is what I get on update:

GPG error: https://packages.kopia.io/apt stable InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 2273699AFD56A556
E: The repository ‘http://packages.kopia.io/apt stable InRelease’ is not signed.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
