Hi! Using the atmel_sama5d3_xplained_mmc_defconfig configuration, it is complaining about a missing MPC source package as of ab4f3fafaa839593b3efd9ea12c8ee5d9340cdeb, see http://toolchain.lug-owl.de/laminar/jobs/buildroot-atmel_sama5d3_xplained_mmc_defconfig/6
Jan-Benedict, All, Thanks for the report, but this is probably a spurious issue on your side: 1. It first tries to reach the GNU official site: [build 2023-09-23 03:45:52] --2023-09-23 03:45:52-- http://ftpmirror.gnu.org/mpc/mpc-1.2.1.tar.gz [build 2023-09-23 03:45:52] Resolving ftpmirror.gnu.org (ftpmirror.gnu.org)... 209.51.188.200 [build 2023-09-23 03:45:52] Connecting to ftpmirror.gnu.org (ftpmirror.gnu.org)|209.51.188.200|:80... failed: Network is unreachable. 2. then it falls back to trying on Buildroot's backup site: [build 2023-09-23 03:45:52] --2023-09-23 03:45:52-- http://sources.buildroot.net/mpc/mpc-1.2.1.tar.gz [build 2023-09-23 03:46:12] Resolving sources.buildroot.net (sources.buildroot.net)... failed: Temporary failure in name resolution. [build 2023-09-23 03:46:12] wget: unable to resolve host address 'sources.buildroot.net' 3. for legacy reasons, Buildroot tries the old URL, which fails because indeed that is not where we nowadays stores mirrored archvies: [build 2023-09-23 03:46:12] --2023-09-23 03:46:12-- http://sources.buildroot.net/mpc-1.2.1.tar.gz [build 2023-09-23 03:46:19] Resolving sources.buildroot.net (sources.buildroot.net)... 104.26.0.37, 104.26.1.37, 172.67.72.56 [build 2023-09-23 03:46:19] Connecting to sources.buildroot.net (sources.buildroot.net)|104.26.0.37|:80... connected.

In this case, the issue is really somewhere between your machine and the network. Regards, Yann E. MORIN.
