make: *** [Makefile:45: build] Error 1

I assume that the /srv refers to inside the Docker image, right? In fact, nothing is produced in the installation /srv/ directory. I've tried to change its permissions, but the same error persists.

OS: Ubuntu 22.10

Docker version: Docker version 20.10.16, build 20.10.16-0ubuntu1

The problem is a mismatch between the local user (UID=1001, GID=1001 in my setup) and the jekyll user (UID=1000, GID=1000) inside the Docker image. If their ids match, this error should not be observed.
