If Server A and Client B are chatting through sockets, and Client B requests a dataset of all accounts on the server it has access to, the server provides that data set to the client (through serialization and sending it over the socket) and the client modifys the data, say it changes a contact name or address or whatever on one or many different records, and sends the dataset back to the server so that the server can update it's records..there a built-in method to compare the two datasets and perform those updates on the parent data source?Check out this diagram for what I mean: That's the general idea, but I'm trying to get the 3rd step to be a little less complicated than comparing row by row each update. Have the client receive the dataset, and then use a table adapter and bind the dataset to the form and when the client clicks the "save" or whatever button, just extract the SQL methods from the table adapter for the insert, update, delete and transmit the SQL commands over the wire, and have the server perform them?
Turns out that a new update (which reintroduces an old bug) causes network manager to crash.

It will update network manager That should launch it whenever your system starts.
A better way would be to add it to the appropriate init scripts so that it doesn't start in single user mode, but honestly it won't hurt anything this way either.
I just had what I think was the same problem OP had, starting manually the Network Manager provided me with the icon in unity, but no interfaces visible, while the above mentioned command and a reboot fixed the issue completely.My install completed successfully, but I got the same error.When I try on the latest version installed, the mice didn't work.When I try with previous version and go in gnome-network manager it's said: Package distributor has shipped an updated version. Your options are: Y or I:install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation The default action is to keep your current version. Write failed: Broken pipe If on 14.04 LTS and you are facing problems after update in 2016 or later use this.I updated on 13th May 2016 and started facing this problem.askubuntu.com/a/771841/543358 This solved the problem without the need to downgrade.
