"Upgrade to this version is prohibited. Use clean install" CPUSE notification
When importing the new upgrade package via CPUSE Online - "Check for Updates" the package metadata became corrupted during the download, therefore CPUSE cannot extract it and prohibit the upgrade/installation.
Checking the files in the metadata folder by running "ls -hlart /var/log/CPda/metadata/" shows that the files size is 0.
For example /var/log/CPda/metadata/CheckPoint#Major#All#6.0#4#9#R80.20_Mgmt/Check_Point_R80.20_T101_Fresh_Install_and_Upgrade_Security_Management_METADATA.tgz)
