Utime failed: Operation not permitted

[MarkE]

Brief background: the live site is on a shared hosting service. I started developing on that but decided to continue it off-line. The development site is on  W10 machine using Xampp. I had no significant trouble setting that up - importing the database using phpmyadmin. I then added a test environment on a Linux box (actually a Pi) running apache2 which is on the private network. I have done this (not with PW) a several times before and it has worked fine.

So I exported and imported the database and copied over the files. After a few problems, I got everything running. However, I am getting one persistent warning, only in the test environment:

Warning: touch(): Utime failed: Operation not permitted in /media/main/web/processwire/wire/core/FileCompiler.php on line 391
Any clues as to what is causing this?

Delete cache folder. Error will be gone.

Thanks guys. I'll make a note not to include the cache folder in deployments.
