Whenever I attempt to install i2p on whonix workstation using the guide on this site i have a problem with i2p not installing.
at this step:
‘3. I2P installation. A.’
i run this command: ‘sudo apt update && sudo apt full-upgrade’
i get this output:
W: GPG error: http :// ppa.launchpad . net/i2p-maintainers/i2p/ubuntu lunar InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY AB9660B9EB2CC88B
E: The repository ‘http :// ppa.launchpad . net/i2p-maintainers/i2p/ubuntu lunar InRelease’ 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.
How can I fix this and get i2p installed on my whonix workstation?
Thank you.
