I have installed headless dropbox as described here
Also downloaded the Python management script and put it in /usr/local/lib as /usr/local/bin/dropbox
Created the following configuration file in my home directory - ~/.config/systemd/user/dropbox.service The content of the service is here - https://pastebin.com/uY7YiH0n
Then I enabled the service and started it and everything is fine.
The problem appeared when I reboot the machine and the service was not started.
systenctl --user status dropbox.service returns
● dropbox.service - Dropbox deamon
Loaded: loaded (/home/georgi/.config/systemd/user/dropbox.service; enabled; vendor preset: enabled)
Active: inactive (dead)
journalctl --user-unit dropbox.daemon returns https://pastebin.com/TjsfZK6x
I have no clue how to make the daemon start
