A Plesk upgrade fails with the following error at the bottom of
memory alloc (4 bytes) returned NULL. ERROR: Failed to run the Yum utility. The Yum utility failed to install the required packages.
The following warning from the Parallels Plesk pre-upgrade checker is also present in the same log file and was displayed in the Parallels Updater web interface before the upgrade started:
