Easy upgrade

Yea that upgrade is easy to start by

omv-update && omv-release-upgrade

but it stopped on my system with the message that sed had an issue within configuration step of openmediavault.

Expensive mistake in openmediavault.postinst script

Well either there was really a mistake, or my /etc/openmediavault/config.xml file was simple wrong at the position to query the /system/notification/notifications/id in file /var/lib/dpkg/info/openmediavault.postinst.

Issue was

xmlstarlet sel -t -m "/config/system/notification/notifications/*" -v "name(.)" -n -b /etc/openmediavault/config.xml | xmlstarlet unesc

didn’t found the id in my config.xml. So I changed it after hours of searching to

xmlstarlet sel -t -m "/config/system/notification/notifications/*" -v "id" -n  /etc/openmediavault/config.xml | xmlstarlet unesc

Take a look to the

                if dpkg --compare-versions "$2" lt-nl "3.0.15"; then
                        # Modify the notification settings.
                        xmlstarlet sel -t -m "/config/system/notification/notifications/*" \
                          -v "id" -n \
                          ${OMV_CONFIG_FILE} | xmlstarlet unesc |
                          while read id; do
                                  enable=$(omv_config_get "/config/system/notification/notifications/${id}")
                                  object="<uuid>$(omv_uuid)</uuid>"
                                  object="${object}<id>${id}</id>"
                                  object="${object}<enable>${enable}</enable>"
                                  omv_config_add_node_data "/config/system/notification/notifications" "notification" "${object}"
                                  omv_config_delete "/config/system/notification/notifications/${id}"
                          done

After this small change it’s working and the package openmediavault is configured successful.
