We had Ubuntu Server 10.10, after upgrade to Ubuntu Server 11.04 some applications doesn't works by example "Printing" on "Sysmte- Administration" and User Administration GUI, how can I fix it?
You need to tell us more about what applications are failing and how they are failing? Core dump? Just not working or what?
I don�t know the name of the appl, I think that with the upgrade the app is not installed, by example one of them is the appl that show the printers connected to the system, and by there you can install o remove, modify any printer, the other can be used to add user, modify user, delete user, I don't know much about Ubuntu, I'm new on it.
