Today I downloaded the present debian-live-11.5.0-amd64-gnome.iso via my prepared script

The final check
   sha512sum --ignore-missing -c SHA512SUMS
resulted into
   debian-live-11.5.0-amd64-gnome.iso: FEHLSCHLAG

Already since some years, the check

This may be my own problem, because I haven't got a book to learn gpg.

The SHA512SUMS file came directly from
https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/SHA512SUMS
The SHA512 of debian-live-11.5.0-amd64-gnome.iso is then

which matches the line in the SHA512SUMS file
450d09f1f1556effce4bc072ad395e45652aa40ed035b8ab35616c54fbef0c6edf803acb483ac25737b12bbae858277c1aa261eee36c4edf505a85c915d73c67 debian-live-11.5.0-amd64-gnome.iso
So do you get a different SHA512 from your downloaded debian-live-11.5.0-amd64-gnome.iso ?
Or does the downloaded SHA512SUMS file show a different SHA512 ?

While copying the logfile I remembered that I used wget twice with "-c" option.

I started my batch by doubleclicking the file in nautilus.
I expected differences in bytes anywhere in the beginning, but comp -l and comp -b didn't showed such result.

I'm using debian bullseye with gnome 3.38 and wayland.
However, I can try your lines the next days.
If you like, I could add the shell selecting in the first line "#...".
So, it seems to be a problem of nautilus on my computer.

nautilus is starting a bash terminal.
After the break it told me a size of 7.900 Byte.
ls -l is telling me 150431900 which is huge for the short download time.
In the terminal start wget startet at ~250 MB which is disturbing me.
Hi,
just for the records i report what Gerd Mühlenbruch and i found out
off list:
The reason for the bad dowload was that two wget processes were writing
to the same file.
Gerd had started the first wget by letting nautilus executing it. For
this it created a terminal window with a running wget, which Gerd soon
after closed by means of the desktop.
Then he wanted to continue downloading by starting wget in terminal
window.
Closing the nautilus-made terminal would normally shut down the program
that is running in it. Not so with wget, where the man page says:
Wget is non-interactive, meaning that it can work in the background,
while the user is not logged on. This allows you to start a retrieval
and disconnect from the system, letting Wget finish the work.
We did not explore what exactly causes the oversize of the download result. >The situation of two simultanously working wgets on the same file is ill >enough to serve as explanation.
Have a nice day :)
