When typing either of the commands
nautilus . or
xdg-open . into terminal, they execute correctly, but with a warning:
Nautilus-Share-Message: Called "net usershare info" but it failed: Failed to execute child process “net” (No such file or directory)
As I say, it opens the file manager correctly and I can detect no further problems. There are several instances of users experiencing this message in other questions (1)(2)(3), but each of the questions either addresses a side-issue I'm not experiencing, or simply goes unanswered.
What does this message mean, and can I do anything to prevent it?
