after I got this error (sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set ) for my user account. To resolved it I executed this (chown root:root /usr/bin/sudo && chmod 4755 /usr/bin/sudo). But now when I am using the lockscreen my password is not working. *** /usr/lib/kscreenlocker_greet --testing: file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreenUi.qml:599: TypeError: Cannot read property 'longName' of undefined file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/components/UserList.qml:43:9: Unable to assign [undefined] to bool qt.virtualkeyboard.hunspell: Hunspell dictionary is missing for "en_US" .

If you got this error to begin with, I suspect you have a system that is set up unusually. Can you provide some details about your distro, installation procedure, PAM setup, any manual configuration changes, etc? Anything that might be relevant.
