I tried this. It didn't work. Same error as before.

Read 8.2.12 of the Putty help file - had no idea there was a format 
difference I had to do anything about! Tried what it said to do, use 
Conversions: Export to OpenSSH. But that key looks like:

Ltsdo-adefaria:more /tmp/sshkey

Whereas all of the lines of my ~/.ssh/authorized_keys files are single, 
loooong lines. This doesn't look like it'll work... Tried it. It didn't 
work either.

Can anybody give me clear, concise but complete end to end instructions 
on how to get this to work?

Drive carefully. It's not only cars that can be "recalled" by their maker.%
