The sysupgrade based upgrade instructions suggest the following example for a sysupgrade:
cd /tmp wget http://downloads.openwrt.org/chaos_calmer/15.05/****/generic/filename-of-downloaded-sysupgrade.bin
sysupgrade -v /tmp/filename-of-downloaded-sysupgrade.bin
My router's page on OpenWRT Techdata: Linksys WRT1900ACS v1 suggests that the "Firmware OpenWrt Upgrade URL" is https://downloads.openwrt.org/chaos_calmer/15.05.1/mvebu/generic/openwrt-15.05.1-mvebu-armada-385-linksys-shelby-squashfs-sysupgrade.tar -- a tar rather than a bin -- I don't know if this is important - it is not.

Looks like The Let's Encrypt cert isn't good :(

It looks like the tar file I'm using is no good. Should there be an alternative bin file? Or what else would you suggest?
Update:
I've tried this again with the Lede details for my router - this time a .bin file...
cd /tmp wget --no-check-certificate https://downloads.lede-project.org/releases/17.01.4/targets/mvebu/generic/lede-17.01.4-mvebu-linksys-wrt1900acs-squashfs-sysupgrade.bin
sysupgrade -v lede-17.01.4-mvebu-linksys-wrt1900acs-squashfs-sysupgrade.bin
I get the same errors at the bottom of the output:

Looking further, it's this bit thats failing: Cannot parse config file
And seems to be something thats [been seen before]](https://forum.openwrt.org/viewtopic.php?pid=298046#p298046) to do with my router having a kernel1 and kernel2 in /proc/mtd
Instead of one device "firmware" or "linux" defined in /proc/mtd, in WRT1900AC and WRT1900ACS we have two of them: "kernel1" and "kernel2" which are redundant. When current firmware is running on first, upgrade should be flashed on second. Then there is a possibility to go back if something will go wrong. After flashing it's needed to switch to second flash.

I'm at a loss as to what the next step is for upgrade. Any help or comments are very welcome.
