Hello Cyril, Thank you for your reply.

The error message : Certificate verification failed. The certificate is NOT trusted. I think ca-certificate is not loaded/used. For me it's an issue about missing root certificate. I tested with your suggestion to use mirror/protocol=https in command line and it works fine :). I try again without mirror/protocol=https and the issue reappears To reproduce the issue : - Start Debian netinst - Use Graphical expert installation mode - At the step " configure the package manager" chose https. - Use default option Thie issue should be reproductible. Could you try ? Note : To avoid doubt, I use ISO as you listed.
