I don’t recall ever being prompted to set a password for root during installation of Silverblue 33. I did set a LUKS passphrase at install time. Post-install I was prompted in the GNOME Initial Setup utility to create my normal (non-root) user account—but that’s it.
The LUKS password doesn’t also double as the one for root, right?
And is there a distinct procedure for resetting root’s password on Silverblue? If not, is it enough to follow one of these standard reset methods?
Assuming that your regular user has administrative rights (typically via wheel group) , which it typically will, you can just user sudo.
To confirm you have admin rights, you can use following command:
id
which will output something like:
uid=1000(myuser) gid=1000(myuser) groups=1000(myuser),10(wheel)
If you are a member of an admin group, like wheel, simply use sudo to reset the root password:
sudo passwd
Hopefully that works for you. This should be same for silverblue as well as fedora proper.
