Re: sha512sum-error at debian-live-11.5.0-amd64-gnome.iso

Hi,

I think I found the reason.
  While copying the logfile I remembered that I used wget twice with 
"-c" option.
  After downloading the first bytes, I remembered, that my batch 
terminal will close automatically. So I stopped my batch and started it 
again in a terminal. Now "weg -c" continued to download the file.

I downloaded the file again at once and now the test works fine.

Many thanks

  Just for information:

"cmp" showed a difference in size:
     cmp debian-live-11.5.0-amd64-gnome.iso 
Err-debian-live-11.5.0-amd64-gnome.iso
     cmp: EOF on debian-live-11.5.0-amd64-gnome.iso after byte 
2910683136, in line 11367081
"ls" told the same:
-rw-r--r-- 1 ghdm ghdm 2911003302 Sep 10 13:49 
Err-debian-live-11.5.0-amd64-gnome.iso
-rw-r--r-- 1 ghdm ghdm 2910683136 Sep 10 13:49 
debian-live-11.5.0-amd64-gnome.iso


Nevertheless I added LANG=C and run the pure test on the first iso file 
just for translation.
