I've got a pinebook (https://www.pine64.org/?page_id=3707) with KDE Neon on it (Ubuntu based OS as you may already know). To my surprize I can not find a remote access software that will install on it. IE: I tried proprietary Teamviewer.deb and it failed. There doesn't seem to be any similar software in it's software centre. Any one out there have a solution perhaps?

Thanks.

Check, if Your teamviewer.deb is compatible with 64-Bit ARM.

Example:
$ dpkg --field /var/cache/apt/archives/wget_1.18-5+deb9u2_amd64.deb Architecture

Result:
amd64

AMD64 is not ARM. Would be incompatible.

maybe ask NSA whether they have remote access via intel ME engine.
