  They released another version recently? Might explain
why my last "apt update" said something about a repository change.

 Might work faster if one first unpacks the archive, then block copy it
to the card. Otherwise it may be so I/O bound that you are getting one
chunk from the archive into the pipe (can the pipe hold enough for 4MB?),
/then/ the pipe gets emptied, and the delay for the next chunk has the
card/OS flushing I/O channels (and maybe triggering card wear leveling and
allocation unit swapping).
