Re: repomd.xml cannot verified at repo openh264/F26

Hi, At Beginning, I imported the gpg key. And I don't modify gpg keys. The log is: $ rpm -q gpg-pubkey --qf '%{name}-%{version}-%{release} --> %{summary}\n' | grep -i 64DAB85D gpg-pubkey-64dab85d-57d33e22 --> gpg(Fedora 26 Primary (26) <fedora-26-primary(a)fedoraproject.org <mailto:fedora-26-primary@fedoraproject.org>>) $ sudo dnf upgrade -v Loaded plugins: builddep, config-manager, copr, debug, debuginfo-install, download, generate_completion_cache, needs-restarting, playground, repoclosure, repograph, repomanage, reposync, system-upgrade DNF version: 2.5.0 cachedir: /var/cache/dnf repo: using cache for: robberphex-kitematic not found deltainfo for: Copr repo for kitematic owned by robberphex not found updateinfo for: Copr repo for kitematic owned by robberphex robberphex-kitematic: using metadata from Wed May 31 03:48:48 2017 CST. repo: using cache for: adobe-linux-x86_64 not found deltainfo for: Adobe Systems Incorporated not found updateinfo for: Adobe Systems Incorporated adobe-linux-x86_64: using metadata from Thu Apr 27 15:15:24 2017 CST.
