Here is the error log i got during the upgrade :
The installation has encountered a unrecoverable internal error. For further assistance report the following information to your support provider.
Installation appeared to hang while executing "/usr/local/cm/script/220.127.116.110-3/cm_app_services_post.sh W1 PostInstall 18.104.22.1680-3 "4.1.3" /usr/local/cm/ /common/download/windows/ /common/log/install/capture.txt" (estimated time 0:00:10, lapsed time 0:05:00)
The system will now halt.
I canot find any information about this script nor the error. Does anyone have a clue about this ?
