Is there a step-by-step guide somewhere for checking the pgp signature? I skimmed over the Ubuntu tutorial page linked to above by @Gofannon back in September 2018, but I couldn’t figure out how to apply it to YunoHost. For example, what do I replace in the example command gpg --keyid-format long --verify SHA256SUMS.gpg SHA256SUMS to make it work for YunoHost? Sorry for this n00b question, but I need some fairly explicit instructions some times.
