Can't check signature: No Public key falure when verifying

Ok ive done this like 20 times before and im following the guide so i know that its not me 99%

I have downloaded the iso, derivative.pub and derivative.asc the iso asc the ico sha512sums and iso 512sums.sig.
6 files in total
I run
gpg --verify-options show-notations --verify Kicksecure-.Intel_AMD64.iso.asc Kicksecure-.Intel_AMD64.iso

but i get

Can’t check signature Can’t check signature: No Public key

I run the signify sha512sum check with no problems so im guessing the file integrity is fine but pgp is broken for me. I am maining ubuntu 22.04 so there is that. It also spits unable to locate extrepo-offline-data when i try to install it but thats no issue since
gpg --verify-options show-notations --verify Kicksecure-.Intel_AMD64.iso.asc Kicksecure-.Intel_AMD64.iso
produces Signature verified

You probably failed to import the signing key. Follow carefully the directions here:

(Note that the steps for importing the signing key are broken out into a separate article linked in the above article, so they’re easy to miss if skimming quickly.)

I followed both your guide and this guide

to the teeth, same result on both ubuntu and kicksecure VM
[workstation user ~/Desktop]% gpg --fingerprint
gpg: /home/user/.gnupg/trustdb.gpg: trustdb created
[workstation user ~/Desktop]% chmod --recursive og-rwx ~/.gnupg
[workstation user ~/Desktop]% echo “916B8D99C38EAF5E8ADC7A2A8D66066A2EEACCDA:6:” | gpg --import-ownertrust
gpg: inserting ownertrust of 6

[workstation user ~/Desktop]% gpg --verify-options show-notations --verify Kicksecure-.Intel_AMD64.iso.asc Kicksecure-.Intel_AMD64.iso
gpg: Signature made Thu 12 Feb 2026 11:34:48 PM UTC

gpg: Can’t check signature: No public key
zsh: exit 2 gpg --verify-options show-notations --verify Kicksecure-*.Intel_AMD64.iso.asc

In above output, you didn’t run any command to import an OpenPGP key.
