I have 10 user on my ubuntu 10.04 - one folder called "public" located in one user's documents.

I like to share the folder, so everyone have access to that folder, as it will be the local folder everyone will use.

Under sharing, I get the following error message:

'net usershare' returned error 255: net usershare add: cannot convert name "Everyone" to a SID. Invalid parameter."

What can I do?

If I understand correctly, you only want to share the folder between all the local users on a single machine, yes? In that case, you do not need to involve sharing, because that is for sharing over a local network. Everything you need to do is to modify the permissions of the folder such that anyone can read and write in that folder. For example, you can set

chmod a+rwx folder

anyone will be able to read, write and delete files within that folder. If you set

chmod a+rwxt folder

then anyone will be able to read and write, but only the person who created a file or directory will be allowed to remove it.

The above command is for command line, but you can also set the permissions using the graphical user interface; right-click on a folder, select properties -> permissions.

Yes, doing this the way by the graphical interface, I get the error above, I am unable to change the permissions. I have recreated the folder, and I was allowed to change the permissions, but still have some problems with the created new document in side the folder that is shared.... Hope you understand – Tim Botha Aug 21 '12 at 13:43
