Securedrop: Tails 3 root nautilus backups

[KwadroNaut]

Bug

Can't start nautilus from root terminal

Since Tails 3, you'll have to do something like gksu nautilus to launch a root nautilus. You'll get a GTK-Warning cannot open display: :1 if you have run a root file manager before in the same session

Steps to Reproduce

Actual Behavior

Comments

gksu nautilus from a regular terminal would work. When reproducing this bug, I found that it only happens when having run a root nautilus in the same sesion before.

Was able to reproduce on hardware. Thanks @KwadroNaut!

Seems running gksu nautilus from the regular terminal application would be a more sustainable alternative in the long run.
