Hi, I received an email about the inability to download the current kernel sources from our Vagrant images: % yumdownloader --source kernel ... No source RPM found for kernel-3.10.0-514.2.2.el7.x86_64 No source RPM found for kernel-3.10.0-514.el7.x86_64 I think this is caused by vault.centos.org, not by our Vagrant images: I can see centos-release-7-2.1511.el7.centos.2.10.x86_64.rpm under http://vault.centos.org/centos/7/os/x86_64/Packages/ - perhaps the "7" symlink hasn't been switched to 7.3.1611 yet? "6" points to 6.8 packages, the current release in the 6.x series. Regards, Laurențiu
