Yay, Error 7 when trying to install a Lineage OS update.  Looks like I need to manually update the firmware again. 

F**k it, I'm so sick of this BS that I'm just not gonna update it anymore. 

If my ever more insecure tablet ends up spreading a virus that causes a global meltdown, don't even think about blaming me.  It's all the fault of the Lineage OS team.
