I have the same error messages on 15.04 clients running against a 15.04 server. All have been upgraded through earlier releases. I first noticed the problem in 14.10.
As per the Debian bug report, stopping winbind on the server is a workaround in a simple SOHO type environment that has worked for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1430259 Title: Mounting CIFS share intermittent failure (CIFS error code -5) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cifs-utils/+bug/1430259/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
