@jc21 commented on GitHub (Jul 8, 2025):

This error is very perplexing.. It suggests that the file contents are incomplete, yet I can confirm that the bash script is full and syntactically correct, passing shellcheck as well.

On my production servers (amd64 and arm64) this script runs and completes successfully.

Can you run this on your NAS:

docker run --rm -ti \
 --entrypoint= \
  jc21/nginx-proxy-manager:2.12.4 \
  cat /etc/s6-overlay/s6-rc.d/prepare/30-ownership.sh

The output should be the same as the repo file.

The script was missing a trailing newline, which is common practice. There's a slim chance that it's a problem with your setup, so try using the develop branch build image and see if it's still happening:

nginxproxymanager/nginx-proxy-manager-dev:develop

@focustense commented on GitHub (Jul 8, 2025):

The "unexpected end of file" error is the result of trying to run the S6_STAGE2_HOOK sed workaround described in #3154 on the new version of the ownership script. In the old version, the chown command was on the last line but as of 2.12.4 the last line is a fi, so removing it breaks the loop. Unclosed loop = unexpected EOF.

Lots of discussion in the latest comments on the other thread.
