I am running Ubuntu 20.04 on Windows 10. Running uname -r returns: 5.4.72-microsoft-standard-WSL2. I am trying to run deja-dup, but am having no luck. When I try kicking it off from a Ubuntu terminal, I get the message:
Unable to init server: Could not connect: Connection refused
(org.gnome.DejaDup:29): Gtk-WARNING **: 14:01:49.822: cannot open display:
Searching for how to run it, it looks like most people kick it off using something called Dash (which I am not familiar with). I do have something installed at /usr/bin/dash which when I run it get the following message: dash: 0: Bad substitution
It was awhile ago since I installed Ubuntu, but I don't believe I did anything to it to run apps with a GUI.
Can someone help point me in the right direction?
Thanks.
