linux - sudo: 3 incorrect password attempts Error -

i getting error whenever utilize sudo on terminal, due unable edit file (permission issues) , unable update system. there specific solution without re-installing system?

since seem able login, looks sudo got srewed up. need root password clean mess, otherwise can reinstall. 1 time login root, here things try:

run sudo strace , ld_debug. maybe wrong library installed, or of import file got removed somehow. 1 time identify problematic file, seek reinstall bundle belongs to.

check sudo config files (/etc/sudoers or whatever man sudo mentions). if have modified these files recently, revert changes.
