Plesk inside the provisioned VE is installed successfully and there are no errors inside /tmp/autoinstaller3.log (for Linux) or C:\ParallelsInstaller\autoinstaller3.log (for Windows) in the VE.


Under certain conditions, Plesk installation status is returned to stderr instead of stdout, which causes the provisioning task failure. The issue is recognized as CCU-14504.


Re-run the task until it is successful. The mentioned error does not represent real issues behind it.
