not booting from sd card

[bcnaz]

Thanks, bcnaz!

I'm confused (as usual ). When you say "flash my sd cards" do you mean flash the phone's internal memory from the sd card? Or install the OS on the sd card and then boot from the sd card?

I've never used dd before. It's such a brute force method, I get the feeling it makes the cards squirrelly. I'll look and see what Etcher can do. it would be nice to have a more reliable method!

Edited to add: Etcher looks really good. But it won't let me run it. It says my sandboxing is incorrectly set up. It complains about a dir in /tmp which should have 4755 permissions. so I created that dir, chmod to give it those permissions, but still same error msg. I have zero idea what it's really talking about (setuid, I know, but I don't really understand the whole concept).

Be nice if it just worked.

(I run Debian, which can be finicky about permissions. 10, Buster)

   SORRY

I dual boot Debian and Ubuntu 18.04

I forgot I was using Ubuntu and then etcher did   "JUST WORK"

I did a quick search and check,  I could not get etcher to load on my Debian Stretch ether.
