Rudder

It could be that there is a conflict between rudder-server-root and rudder-agent.

If I try to install rudder-agent 2.4 on a Rudder server 2.3 an error about the owner of the configuration file /opt/rudder/etc/uuid.hive :

root@squeezedev:~# aptitude install rudder-agent 
The following NEW packages will be installed:
  rudder-agent{b} uuid-runtime{a} 
0 packages upgraded, 2 newly installed, 0 to remove and 10 not upgraded.

The following packages have unmet dependencies:

• rudder-agent should be installed before rudder-server-root in 2.4 branch
• rudder-server-root must be migrated before in order to allow rudder-agent to be installed (if not the conflict about the config file uuid.hive will appears like above)

It could be related to this issue, because:

• rudder-agent should be installed before rudder-server-root in 2.4 branch
• rudder-server-root must be migrated before in order to allow rudder-agent to be installed (if not the conflict about the config file uuid.hive will appears like above)

It could be due to an instruction missing in the control file like Replaces and/or Breaks about rudder-server-root in the rudder-agent-control (cf http://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces).

Looks good to me ! Thanks NPE :D

I'm not convinced that this adresses the problem originally described, but there is not enough information to do anything about that. The fix is valid, and necessary, so I'm validating this one.

If I remember, the problem was that rudder-agent wasn't installed (and didn't replace rudder-cfengine-community) before upgrading rudder-server-root, which failed because of missing dependencies.
