Instructions aren't current with Qt's online docs and source code

[tbrowder]

I'm trying to follow instructions to install your patched Qt. Finally, I got the separate qt repo into the wkhtmltopdf repo (I probably should have made it a git submodule, but haven't yet). Then I tried:

./build package-docker buster-amd64 ../wkhtmltopdf

and got:

Error: remote trust data does not exist for docker.io/aptman/qus: notary.docker.io does not have trust data for docker.io/aptman/qus
docker pull --platform linux/amd64 aptman/qus:d5.0
command failed: exit code 1

I do not know much about docker and would appreciate knowing how to proceed.

For many years I have enjoyed using wkhtmltopdf on Linux via a screen grab, but being able to script it on a remote host would be wonderful!

Note I am a long-time Perl (since 1993) and now Raku user (since 2015), but I've also had to create or maintain Fortran, C, and C++ libraries for necessary jobs at $work. But it's been over 15 years since I've had to compile Qt and it was NEVER any fun.
