You have first of all to install the public-key of KDE-Neon:
- downloading it (it is a text file such as
armored-keys.asc
) - and installing it gpg –import [your-downloaded-public-key-file]
Then you have to go into the folder where are both iso and sig files and give this command
gpg --verify [your-iso-file-name].iso.sig
You should see something like:
gpg: assuming signed data in 'neon-user-20200813-1119.iso'
gpg: Signature made �� 16:40:21 PKT �� 13 �������� 2020
gpg: using RSA key 348C8651206633FD983A8FC4DEACEA00075E1D76
gpg: Good signature from "KDE neon ISO Signing Key <neon@kde.org>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg: There is no indication that the signature belongs to the owner.
