I/O errors during 4.2 build

[Skip Pack]

Hello -- I have been trying to build 4.2 and have repeatedly encountered similar errors. This is on an RPi3+. I install the strectch lite image (correct date) and start the process without difficulty. The most recent instance is a while after reboot 2:

Processing triggers for install-info (6.3.0.dfsg.1-1+b1) ...

dpkg: unrecoverable fatal error, aborting:
 unable to fsync updated status of 'nginx-common': Input/output error
E: Sub-process /usr/bin/dpkg returned an error code (2)
** Error: Install failed
** Error: image build exited
** Error: reboot to resume the build

Other occurences are similar (not identical) but the location varies from relatively  early after the power-cycle reboot to much later as shown here. All are Input/output errors. I successfully installed 4.1 many times on this hardware.

Your thoughts are very welcome.

Have you tried another microsd? I had a relatively new 32gb card go bad (well, get obnoxiously slow which I assume is due to error correcting going crazy).

Thanks, that did the trick. I have HughesNet satellite service and there are delays between packets that I suspect may also contribute to these kind of issues. I think the sdcard that completed the build my be a little faster, as well.
