Somehow I lost my root password under Kubuntu 20 :
$ sudo -s [sudo] password for master: Sorry, try again.
I do not think I forget it. It is simple “1”.
It is my home laptop - nobody else has access to it.
Any ideas how can I restore it?
When loading OS some menu options on loading ?
Usually I have installed firewall w3ith options like :
sudo ufw status verbose Status: active Logging: on (low) Default: deny (incoming), allow (outgoing), disabled (routed) New profiles: skip To Action From -- ------ ---- 80,443/tcp (Apache Full) ALLOW IN Anywhere 80,443/tcp (Apache Full (v6)) ALLOW IN Anywhere (v6)
I failed to run it now as I can not login under root ?
