i achieve to uninstall and purge rpcbind, after deleting some configuration files that i modified.
the big problem was rpcbind prevented the system to be stopped cleanly. after reinstalling, everything is ok, but rpcbind reproduces bug 835833 https://bugs.launchpad.net/ubuntu/+source/rpcbind/+bug/835833 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/983236 Title: package rpcbind 0.2.0-7ubuntu1 failed to install/upgrade: el subproceso s'ha instaŀlat el script pre-removal se mató con la señal (Matat) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rpcbind/+bug/983236/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
