[davide]

ubuntu 14.10. All packages are updated to the last release.
some problems with a lot of packages: cups, nfs-common, nfs-kerne-lserver, rpcbind. I have to use my usb printer epson 9400f but i can't. I've tried lprng. When i try to install one of this packages the error is "sub process /usr/bin/dpkg returned an error code (1)"
