I haven't seen it before but the file is exactly 4096 bytes smaller
than the number of blocks it has.
$ stat $file
... Size: 810549248 Blocks: 1583112 ...
( and 810549248/512 = 1583104 = 1583112 + 8 )
For me, "du" reports from the blocks count 1583112/2 = 791556, while
"du --apparent-size" reports from the byte size 791552 = 810549248/1024
files.devuan.org (which is the ultimate source) has an ext4 file
system, if that's att all relevant.
The sha256sum should still be as per the .shasum file, and my download
from
http://mirrors.dotsrc.org/ does offer that sha256sum
you may need to download again.
