If the default guest user which is created during installation trys to power
down an UCC thinclient with the LXDE button designated for it, the system
freezes at a certain moment during the shut down process (see screenshot) and
can't be pinged anymore.

This might be caused by a general problem which currently occurs when shutting down an UCC system with active NFS mounts.

The UCC system deconfigures it's network device but then still attempts to reach the NFS server on the UCC master - in an endless loops as it can't be reached without network connectivity.
Comment 2 Erik Damrose univentionstaff 2013-01-16 10:20:25 CET
This happens only when the client is booting a 'live-system'
Comment 3 Erik Damrose univentionstaff 2013-01-16 17:16:23 CET
To fix it i changed the shutdown order of networking when working with a livesystem. Network now stops after unmounting all filesystems.
Comment 4 Moritz Muehlenhoff univentionstaff 2013-01-28 14:47:02 CET
I could successfully shutdown the live-booted thin client and desktop images.
