hi, Real Bug is that NFS logging dose not give clear information wgat's happening and diagnose is hard to do!
Problem solved: 1) I finaly found upgrade kernel, after installing it gssapi error message dissapeared and NO ERROR MESSAGES at log's. 2) by useing wireshark I found _kerberos._udp DNS requests and due DNS had not answers I configured BIND9 to publish all kerberos service addresses. I have NFS + MIT kerberos client and apacheDS LDAP + KERBEROS server there is no addministration address at kerberos. joni ** Changed in: ubuntu-release-upgrader (Ubuntu) Status: New => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1373490 Title: NFS4, NFS stopped working after 12.04 to 14.04 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1373490/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
