Hey guys. I’m new to Linux and I’m running Linux Mint 21.2 Cinnamon. Yesterday I have f*cked up. I was testing things in users and geve myself standart priveledges insted of Admin ones I had from beggining and then restarted PC. I then tried log back into users tab and change myself back to Admin but even tho the password is correct It says that it is not. /So at this point there is only one user in PC who has standart privliedges and no Admin./ I then tried to access root via terminal and this time It said that I don’t have permision to do that. And this is where I’m at right now. Please help get back my admin privliedges.
Edit: Issue is fixed. I started GRUB and changed my password which fixed the whole issue. Once again big Thank you to everyone who gave me tips and also big thank you to the guy who started posting about rowing machines. You all wonderful.
I’ve had to set it up manually. May depend on the distro, I suppose. su won’t work without the root password.
When I’d set systems up, creating a password for the automatically created root account was one of the first steps in the process after setting up the basics. You could then set other accounts to have root privileges, or set up sudo to allow your personal account access via sudo, but even sudo acts as UID 0. If your setup didn’t do that, or if you set your account name up as UID 0, then you can always boot off of another source and mount the internal hd, right?
It’s a matter of distro and the installation process. I must note, I installed Linux dozens of times from 1999-2012 and not as much since then. Back then, while of course one set the root password, it didn’t ask about sudo privileges during installation of Debian, Ubuntu or Mandrake. And yes, that’s true, you can always boot from a different installation (such as a Live CD) except it is more complex if it is an encrypted filesystem.
