Which mirror? If its certificate has been emitted by one of the usual
CAs (see the ca-certificates package[1]), I don't think you should be
getting any trust issue.

 1. https://tracker.debian.org/pkg/ca-certificates

The last upload of this package is dated 2021-01-19, migration to
testing 5 days later, and it's included in D-I Bullseye RC 1, which I've
tested successfully against an HTTPS mirror, so the basics should be
good, unless some other component broke in the meanwhile.

Is the clock set up properly on that machine? Besides not having the
right CA(s) configured, an offset of the clock side can lead to trust
issue as well (certificate not yet valid or already expired).

There's nothing wrong with reporting a possible issue, don't worry.

For my regular installation tests, I'm tweaking the kernel command line
before starting the installation process. There might be better ways,
I've just been using that for so long that I didn't perform any research
lately. :D

Setting this is sufficient:


You'd probably get to the mirror selection stage with the “manual
setting” choice set and deb.debian.org as hostname and /debian as
directory. You can deviate from those in that particular screen, or you
can also preseed those settings with those variables, also on the kernel
command line:


As usual, use space as a separator between each parameter passed on the
kernel command line.

For the avoidance of doubt, this matches this specific ISO:

And I've just tested an installation successfully by setting:


then using mostly default choices.
