The same issue was also observed on the development shapshot build for the bcm53xx target. Sorry, I should have mentioned it in my original bug submission earlier today. The image I used for testing was downloaded on 2017-10-01 from:

http://downloads.lede-project.org/snapshots/targets/bcm53xx/generic/lede-bcm53xx-buffalo-wxr-1900dhp-squashfs.trx

The downloaded image was installed with "sysupgrade -v -n ./lede-bcm53xx-buffalo-wxr-1900dhp-squashfs.trx". I made no configuration changes in any of the files in /etc/config/ after installing the downloaded image.

I also tested this issue on my own LEDE build, LEDE Reboot SNAPSHOT r4967-5508510. The result was the same: "“Command failed: Unknown error".
