Using Ubuntu 24.04.4 LTS

I ran apt update and got:

The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY A189E93654F0B0E5
Reading package lists… Done

4 packages can be upgraded. Run ‘apt list --upgradable’ to see them.
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://apt.hestiacp.com noble InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY A189E93654F0B0E5

W: Some index files failed to download. They have been ignored, or old ones used instead.

Any idea?

Run this command and try again:

curl -s "https://apt.hestiacp.com/pubkey.gpg" | gpg --dearmor | tee /usr/share/keyrings/hestia-keyring.gpg > /dev/null
