hash error [OpenWRT+OpenFlow1.3 for TP-LINK WR1043ND v4.0]

[pureise]

Hey, I'm trying to install openwrt (trunk) and openflow 1.3 on TP-LINK WR1043ND v4.0 on my Ubuntu 18.04 and I'm getting some errors about hashes, I've quoted it down below. There was already a similar problem on here, but it was closed after no response, it was about LEDE and the possible fixes from there didin't work for me unfortunately.
Please forgive me if anything about my post is wrong, I'm all new to all of this :)
