hello, I have a problem with connecting to the VPS, when installing the server on cs 1.6, it was impossible to connect, I entered the following commands: systemctl stop ufw, systemctl stop firewalld, Iptables -F, and then it worked, unfortunately, when installing another thing, the machine turned off again in the sense that it was impossible to enter through port 22, I type the same commands, and it tells me I don't have permissions, I try to give sudo or sudo su before that and still no.
Version: Ubuntu latest
The error that pops up:

bbuser@BaseBuilder:/root$ systemctl stop ufw ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units === Authentication is required to stop 'ufw.service'. Authenticating as: Ubuntu (bbuser) polkit-agent-helper-1: needs to be setuid root Error: Incorrect permissions on /usr/lib/policykit-1/polkit-agent-helper-1 (needs to be setuid root) ==== AUTHENTICATION FAILED === Failed to stop ufw.service: Access denied See system logs and 'systemctl status ufw.service' for details.

    the following can be a solution according to the error

    add abuser to the sudoers group 

    add line 
bbuser ALL=(ALL:ALL) ALL

    check the sudo configuration as bbuser if there is an issue

    sudo -l

    The error message mentions that /usr/lib/policykit-1/polkit-agent-helper-1 needs to be 'setuid root'. Change this by

    chmod u+s /usr/lib/policykit-1/polkit-agent-helper-1
