I installed Samba on Ubuntu 14.04 LTS, and since I running it off USB stick - was able to share the "Downloads" folder on my local network. However, if I try to share a folder on any mounted drive (FAT, or NTFS, Internal or External USB), I get the same warning:
"Nautilus needs to add some permissions to your folder "the_break" in order to share it"
"The folder "the_break" needs the following extra permissions for sharing to work: - read permission by others - write permission by others - execute permission by others Do you want Nautilus to add these permissions to the folder automatically?"
Hitting "Add permissions automatically" closes that dialog, and I can see the share, but cannot access any files in it. Mounting manually as described in https://superuser.com/questions/161649/sharing-a-folder-with-nautilus-and-ntfs-external-drive-gets-errors did not seem to work, or I did it wrong for my enviroment ...
