I have a fresh install of a Linux system and I cannot link the app to my computer (UbuntuStudio 20.04 - XFCE4) as the "sign in" from the dropbox icon in the notifications area does nothing when pushed, it also displays "waiting to be linked to a dropbox account". If I enter preferences and view the "account" I can see "This computer isn't linked to an account" but I get no option whatsoever to login to my account. I have tried uninstalling and installing it again with no luck.
after struggling for a long time with no clear guidance from dropbox, I finaly (by complete chance) ran "sudo dropbox start -i" and got a message I was not getting before that said "To link this computer to a Dropbox account, visit the following url:" this allowed me to finally link my app to my account, but I could not find any type of documentation pointing me this way or even mentioning this. This created a dropbox folder in my root folder, when I try to move it back to my home folder, the app behaves poorly again. I get the same messages from before.
