Hi, new certification problem, this time on buster.
While looking why wget on Debian 8 does not work with lists.debian.org i learn that it does not work on Debian 10 either: $ wget -d https://lists.debian.org/debian-user/ DEBUG output created by Wget 1.20.1 on linux-gnu.

The number of 126 certificates would match /etc/ssl/certs. It's really on buster: $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 10 (buster) Release: 10 Codename: buster The kernel is a modified 5.10.rc3 (i should upgrade to Debian 11 and apply my patches to its kernel source). Is this reproducible on other busters ? Have a nice day :) Thomas
