can't get file transfer working. Help, please!

[quixote]

Progress! No real result, but progress.

Desktop to pinephone says "Permission denied" So somewhere, something about ssh is not set up to let it go. My timestamps on the config files are 2014.... No wonder I don't remember anything. I vaguely recall setting it up to be passwordless and require a key. ??

Pinephone to desktop, after I installed EasySSH, connected beautifully. Cool! Except I can't get the syntax right to copy the files I need. (scream) I'd like to get all four files in subdir "anbox"

so the terminal shows: quixote@desktop:~$

At that prompt, I tried cp ~/anbox/* mobian@10.66.0.10:/home  but maybe I typoed something because it didn't go. I'll try again. Edited to add: nope. I've tried  mobian@10.66.0.10:/home  mobian@10.66.0.10:/home/mobian  mobian@10.66.0.10:/ and it keeps saying "is not a directory."

Walter's sftp method would be good, except for me it just keeps prompting for the password, even though I'm entering the right one. All very frustrating. (I use debian/kde and dolphin file manager. It may not handle sftp as elegantly as ubuntu.)

Thanks for the suggestions! And if you have more, please bring 'em on
