buildroot tries to access curl-7.87.0.tar.xz from its host at https://curl.se/download, fails because the certificate is expired, then tries to get it from http://sources.buildroot.net/libcurl but fails again because the latest version on that site is curl-7.86.0. Adding curl-7.87.0 to http://sources.buildroot.net/libcurl would properly resolve this issue. Thanks. apines@stinky:~/buildroot-2022.11.1$ make /usr/bin/make -j1 O=/home/apines/buildroot-2022.11.1/output HOSTCC="/usr/bin/gcc" HOSTCXX="/usr/bin/g++" syncconfig >>> libcurl 7.87.0 Downloading wget --passive-ftp -nd -t 3 -O '/home/apines/buildroot-2022.11.1/output/build/.curl-7.87.0.tar.xz.ekOKUU/output' 'https://curl.se/download/curl-7.87.0.tar.xz' --2023-01-20 16:55:03-- https://curl.se/download/curl-7.87.0.tar.xz Resolving curl.se (curl.se)... 151.101.1.91, 151.101.193.91, 151.101.129.91, ...

Andrew, All, The sources.buildroot.org is a best-effort mirror, which is automatically populated with a cronjob, and there is no guarantee it is cpmlete. If an upstream becomes unreachable before we can cache it, then there is nothing we can do about it. In this specific instance, the upstream site is working again, with a certificate that is up-to-date, so we should soon see the archive on s.b.o once the cronjob kick in (at least, I could download it manually here).
