Incorrect group used for chown in spec file for repo install via RHEL

[cory-usap]

Environment:

• OS name: RHEL
• OS version: 9
• Architecture: x86_64
• ntopng version/revision: 6.2.250204-25099

What happened:
During install I noticed some lines:

  Running scriptlet: ntopng-6.2.250204-25099.x86_64                                                                                                                                  57/59

/bin/chown: invalid group: ‘ntopng:ntopng’
/bin/chown: invalid group: ‘ntopng:ntopng’

After doing a dnf reinstall the same message persisted.

How did you reproduce it?
Installing the package on RHEL 9 (could be any RHEL based looking at the spec file in stable - if this is the correct one 6.2-stable/packages/ntopng.spec.in).

In particular I ran

dnf install -y ntopng
# and for reinstall
dnf reinstall -y ntopng

Potential fix
The issue seems to be line 6.2-stable/packages/ntopng.spec.in#L202 as on line 158 it creates just an ntop group. It seems like ntop group is the desired one?

I did run

/bin/chown ntopng:ntop /usr/bin/ntopng-config
/bin/chmod gou+s /usr/bin/ntopng-config
/bin/chown -R ntopng:ntop /etc/ntopng

After to be sure permissions were set correctly

Thank you!
