Can't complete installation

[orgitnized]

Hello - I've tried to install this on Ubuntu 24 and CentOS 9 and it fails in the same spot.

I make it almost to the end of the install, and adding the service will yield the following results.

sudo systemctl enable netshot.service
Failed to enable unit: Cannot alias netshot.service as netshot.

The java binary cannot be executed. You should check permissions on /usr/bin/java for netshot system user.

I don't see any issues with permissions. This install was done solely for netshot and was installed under the netshot user account, so it would be hard to believe it was an access issue, but I've added the output in the below code section.

namei -m /usr/bin/java
f: /usr/bin/java

 drwxr-xr-x usr

I've just tried a fresh install on Ubuntu 24.04 and didn't have this issue. Is /usr/bin/java -version fine? Are you well running on x64?

[orgitnized]

I run on arm, not x64. Output looks fine and netshot runs fine, but the service will never install.
