This is a yum/dnf-style repository for Oracle Linux/Fedora/RHEL/openSUSE/CentOS. All .rpm packages are signed. The public key for rpm can be downloaded here. You can add this key (not normally necessary, see below!) with
wget -q https://tho-otto.de/download/rpm/atari-mint-cross.asc sudo rpm --import atari-mint-cross.asc
or combine downloading and registering:
wget -q https://tho-otto.de/download/rpm/atari-mint-cross.asc -O- | rpm --import -
The key fingerprint is
CC2E 22F1 B649 2FD3 EACF F8BF 3C95 69A5 6896 9A28 Thorsten Otto (m68k atari mint signing key) <admin@tho-otto.de>
After importing the public key, the package signature can be checked with
rpm --checksig PACKAGE_NAME
Note that importing the key is not necessary for yum users (Oracle Linux/Fedora/RHEL/CentOS) when using one of the atari-mint-cross .repo files from below as yum downloads and imports the public key automatically! Zypper users should run
sudo zypper refresh
The package signature is checked by yum/dnf/zypper as well:
