[GRASS-user] GUI map save cannot find location

GRASS GRASS user
1

Using the GUI 'save map' button produces this result:

GRASS 7.9.dev (mohler):/data/grassdata > (wxgui.py:9494): Gtk-WARNING **: Failed to fetch network locations: The specified location is not mounted

This same message appears when I try to save the .png to ~/ or the cwd
(/data/grassdata/).

I have not before had any problems saving displayed maps using the GUI.
Please advise.
