Hi all, I would like to build https://github.com/systemd/zram-generator with OBS, and already able to handle packaging for both (see https://software.opensuse.org//download.html?project=home%3Aalvistack&package=zram-generator): - openSUSE Leap 15.3 / Tumbleweed - Fedora 33 / 34 - Debian 10 / 11 - Ubuntu 20.04 / 20.10 / 21.04 Since it is a Rust-based project, when packaging on CentOS 8 Stream I need to `BuildRequires: cargo` which is located in AppStream (see https://centos.pkgs.org/8-stream/centos-appstream-x86_64/cargo-1.52.1-1.modu...). I had add "CentOS:CentOS-8/appstream" as additional repository path under "CentOS_8_Stream" at https://build.opensuse.org/repositories/home:alvistack. Ideally cargo should be found but now display an error message as below (see https://build.opensuse.org/package/binaries/home:alvistack/zram-generator/Ce...): The build can not begin, because required packages are either missing or not explicitly defined. Repository has been published unresolvable: nothing provides cargo May I have some hints about how to install cargo for CentOS 8 Stream, therefore passing the packaging process? Regards, Edison Wong
