Forget ROOT password in Ubuntu20.04 version, reset password
1. Tucao
I just installed the latest version of the Ubuntu operating system some time ago. After playing for two days, I put it aside and busy with other things. When I was about to do something more today, I found that forgetting the password is such an embarrassing thing that I might have forgotten it when I get older. Oh, my heart is so tired! Let’s start serving.
