Why do you think there should be a \n here?

Hello, at the end of the installation, there is : [i] Restarting pihole-FTL service...admin@pihole:/tmp#

[yubiuser]

When this is the last line printed, something is wrong with the installation. It likely fails to restart FTL

The solution should rather be to capture this error and show something useful (like systemctl status)

First comment in this repo else I'd offer to do this for you @DL6ER.

Might I suggest applying this statement as a comment on the one file changed. This would then cause it to be a "Conversation" recognized by the pull request's auto checks that must be resolved, and it would no longer appear as though this PR has met all checks and is merely awaiting an approved review.
