*New Linux user here!*

I just wiped one of my laptops out yesterday and installed Linux/Ubunto. My passwords weren't working, so I did a bunch of research, and here is what I found:

I got to the grub menu and went into recovery mode. Typed:

mount -rw -o remount /
passwd <username>

I entered a password, and was very happy that I was able to use sudo commands once again.

But, I'm back at it this morning (trying to get Zoom to work) and my sudo code is not working! I entered the password that worked yesterday and I get, "Sorry, try again."

I redid the process from yesterday and changed the password to a new one. But that isn't working either.

What do I do now? I spent hours on this yesterday, so it's quite frustrating. Hoping someone will take the time to walk me through this.

Try logging out and logging in again with the new password. Does sudo work then?

Thanks for responding so quickly!
Please forgive my ignorance... will you tell me exactly what you mean by logging out and in? Is that simply closing out of the terminal and opening it again, or is there something more to "logging out"?

No, I mean logging out of the whole system. Use the exit option in your desktop menu. There should be a sub-option for logging yourself out without halting or rebooting.

Logging out of the whole system (desktop environment) such that you have to re-enter your password again to get back in. The reason for that is your desktop environment session is under the old group settings and the changes to the groups won't take effect until you have a new session. That is if you changed group membership for that account in order to get "sudo access".

Perhaps it would help if you could explain the steps you have taken in attempting to restore access.

Thank you! I logged out and back in. The code is working again. I appreciate your help!
