What should I do?

① Was it installed using the root user?
② Please check the system’s GID—has GID 72 been taken?

The pre-install script essentially creates a tcpdump group and user:

%pre
user_id=$(id -u tcpdump 2> /dev/null)

if [ "${user_id}" = "" ]; then
    # Check and create group tcpdump first
    if ! getent group tcpdump &> /dev/null; then
        /usr/sbin/groupadd -g 72 tcpdump 2> /dev/null
    fi
    # The tcpdump group might have been created by another process; the ID is uncertain
    /usr/sbin/useradd -r -u 72 -g tcpdump -d /home/tcpdump -M -s /sbin/nologin tcpdump 2> /dev/null
fi

First, the software installation must definitely be performed using the root user.

Second, I checked and found that neither the /etc/passwd nor the /etc/group file contains a user or group name with UID/GID 72. Additionally, on Ubuntu, I noticed that user or group IDs are 95. Are these dedicated user or group IDs defined individually by each distribution?
