Hi, I try to build a package on Centos8 and I got an issue "unresolvable" I create a test project/package: https://build.opensuse.org/package/show/home:ronan22:test_build_centos8strea... with only one "BuildRequires: python3-devel" And I got a status: "unresolvable" nothing provides python3-devel And I don't understand why. Let's dig a little. My target is (from Meta): <path project="CentOS:CentOS-8" repository="standard"/> And the repository is define as: <repository name="standard"> <path project="CentOS:CentOS-8" repository="appstream"/> <path project="CentOS:CentOS-8" repository="devel"/> <path project="CentOS:CentOS-8" repository="extras"/> <path project="CentOS:CentOS-8" repository="powertools"/> <path project="CentOS:CentOS-8" repository="baseos"/> <arch>x86_64</arch> <arch>aarch64</arch> <arch>ppc64le</arch> </repository> ( From https://build.opensuse.org/projects/CentOS:CentOS-8/meta) and repository "appstream" is define as: <repository name="appstream"> <download arch="x86_64" url="http://mirror.centos.org/centos/8/AppStream/x86_64/os/" repotype="rpmmd"> And this repository had the package: http://mirror.centos.org/centos/8/AppStream/x86_64/os/Packages/python36-deve... Providing python3-devel: # wget http://mirror.centos.org/centos/8/AppStream/x86_64/os/Packages/python36-deve... # rpm -qp --provides python36-devel-3.6.8-2.module_el8.3.0+562+e162826a.x86_64.rpm attention : python36-devel-3.6.8-2.module_el8.3.0+562+e162826a.x86_64.rpm: Entête V3 RSA/SHA256 Signature, clé ID 8483c65d: NOKEY python3-devel = 3.6.8-2.module_el8.3.0+562+e162826a python3-devel(x86-64) = 3.6.8-2.module_el8.3.0+562+e162826a python36-devel = 3.6.8-2.module_el8.3.0+562+e162826a python36-devel(x86-64) = 3.6.8-2.module_el8.3.0+562+e162826a And the repo file (primary.xml) provide python3-devel too: wget http://mirror.centos.org/centos/8/AppStream/x86_64/os/repodata/0ef16342a8153... gunzip 0ef16342a8153c46513e3549e6287de0bdeb0ef4618ac36044d22b0131675d3c-primary.xml.gz rpm:sourcerpmpython36-3.6.8-2.module_el8.3.0+562+e162826a.src.rpm rpm:provides Do you have any idea to solve that? I have got same issue with golang (you can try to add (BuildRequires: go >= 1.11). Best Regards, Ronan Le Martret [IoT.bzh]
