After a clean install this is what I experienced $ sudo dnf update --refresh Circle Linux 8 - AppStream 3.3 MB/s | 7.8 MB 00:02 Circle Linux 8 - BaseOS 2.2 MB/s | 2.6 MB 00:01 Circle Linux 8 - Extras 2.0 kB/s | 2.8 kB 00:01 Dependencies resolved. ========================================================================================================================================================================= Package Architecture Version Repository Size ========================================================================================================================================================================= Upgrading: sos noarch 4.2-19.el8_6 baseos 775 k Transaction Summary ========================================================================================================================================================================= Upgrade 1 Package Total download size: 775 k Is this ok [y/N]: y Downloading Packages: sos-4.2-19.el8_6.noarch.rpm 5.8 MB/s | 775 kB 00:00 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Total 603 kB/s | 775 kB 00:01 Circle Linux 8 - BaseOS 1.6 MB/s | 1.6 kB 00:00 Importing GPG key 0x8A3CB08A: Userid : "circle8-official-key" Fingerprint: 99F3 EA8B BBD8 1D49 5EEC 0BF3 C746 6D73 8A3C B08A From : /etc/pki/rpm-gpg/RPM-GPG-KEY-circleofficial Is this ok [y/N]: This is bad: it trains the user to import GPG keys which can be an unsafe practice. The GPG key should be provided with the ISO
Yes , we test it. $ sudo mount Circle-8.6-x86_64-dvd1.iso mnt/ $ find mnt/BaseOS/ |grep circle-gpg-keys mnt/BaseOS/Packages/circle-gpg-keys-8-7.el8.1.noarch.rpm indeed, circle-gpg-keys include Circle-8.6 ISO. Circle Linux 8.6 add new repo Circle-NFV.repo, and circle-linux-repos provide it. $ rpm -qf /etc/yum.repos.d/Circle-NFV.repo circle-linux-repos-8-7.el8.1.noarch so, while dnf update --refresh, dnf will update circle-gpg-keys and reimport GPG keys. Thanks a lot. Regards.
