I took the "everything" iso and did the dd command to my 16G thumb drive.

I booted and entered my usual ks=http://xxx on the boot line. All good so
It gets my kickstart file and installation begins.
At some point it says

Installing libreoffice-opensymbol-fonts (492/1948)
Retrying download of 1:libreoffice-opensymbol-fonts-

then after 10 retries it fails.

I have verfied this file is on my USB disk, I have re-downloaded from
different mirror, the Everything file, dd that to my USB disk, tried the
re-install and still the error.

I don't know what to try next.
