Rudder

A not accepted node (only applies initial promises). but in latest 2.4.X/2.6 and 2.7 latest promises are not CFEngine 3.5 compliant.

When upgrading that node to 2.8, the node cannot complete the upgrade process because the initial promises are still the one used in 2.4/2.6/2.8

The error message i get when upgrading is:

The solution is to repair the initial promises to be CFEngine 3.5 compliant.

A workaround can be to disable agent before upgrading

touch /opt/rudder/etc/disable-agent
# Upgrade
# sudo yum upgrade rudder-agent
# sudo apt-get install rudder-agent
rm /opt/rudder/etc/disable-agent
