Adding online account fails on E-OS; works on Kubuntu

There’s a nice writeup on KDE Discuss on how to make gdrive working with KDE again.

Problem is: I tried this when I was logged in into my Kubuntu system and got it to work without issues. Naturally, I want to use this under E-OS as well, especially since I mostly use E-OS.

But here, I was unable to.

I added kio-gdrive and it’s dependencies, but when I try to add my Google account in Dolphin under Network, I only get an error (laptop was restarted prior to this after the kio-gdrive installation):

This happens after I tried to add the e-mail address, right before the password screen appears. The ‘userActionFinished error: 2’ remains after further restarts.

Any ideas?
