ensure_path_umounted failed to unmount /efs error after installing an update

I am on Verizon. After I downloaded the security update last I went to clear the cache partition and this error message was waiting me. Anyone else getting this problem.

My S8+ is NOT rooted, BTW.

Mine said that too. Right now everything is working properly so I'm not too concerned. But it is possible to have bugs even in a security update. I'm on AT&T.

Same here. S8, AT&T, never rooted. Talked to Samsung twice. They have no fix and seem to want to ignore the issue.
