When running a cPanel update, you may get the following error:

/scripts/upcp
/scripts/upcp syntax OK
Running Futex Check/Fix……Done
Undefined subroutine &Cpanel::Update::automatic_updates_enabled called at /scripts/upcp line 273.

To fix this, run the following command:

wget -O /root/updatenow.static http://httpupdate.cpanel.net/cpanelsync/RELEASE/scripts/updatenow.static && perl /root/updatenow.static --manual

Then you can proceed running a cPanel update:

/scripts/upcp --force
