I forgot my root password and am attempting to change it by booting into single-user mode, however when booting I get this screen:
Then I press “e” to edit the boot configuration and I get this screen:
However, in the tutorial I’m following it says I should navigate to the line that starts with “kernel”, but as you can see, I dont have this line.
So I tried changing “quiet” to “single” on the line that starts with “linux /boot/vmlinuz….” but this doesn’t boots the system into single-user mode.
What line am I supposed to edit in order for this to work?
My answer:
One method:
-
Append
init=/bin/bashto the end of the grub line which begins withlinux(and ends withquiet). -
Reset your password and reboot normally.
-
Don’t forget it again.
-
Consider installing
sudo.
Another method:
- Since this is apparently a virtual machine, you can mount its disk on another (working) virtual machine and manually remove the password from the
/etc/shadowfile. Or usekpartxto work with the virtual machine image file from the host or from another machine.
