Module Admin fails to remove old module (UCPNODE)

Hello,
Ran Module Admin upgrading what needed to be upgraded for FreePBX 13 (10.13.66-6) but the upgrade of UCPNODE fails as shown:

Downloading and Installing ucpnode
Downloading ucpnode
Error(s) downloading ucpnode:

Could not remove old module /var/www/html/admin/modules/ucpnode to install new version

Thanks.
