Reset lost Jessie root password

[Mr Robot]

So i know this is pretty stupid but i forgot my root password for jessie and now i can't access any root features how do i reset the password?

i've tried booting into recovery mode but it asks for the root password for maintenance

 

thanks in advance

It wouldn't be a good password if you could reset it from recovery, would it? If you have a superuser account you can try

sudo passwd root

I don't think Debian has this blocked by default so it should work.

after i type both passwords it says 

 

passwd: Authentication token manipulation error
passwd: password unchanged

Are you sure you correctly and successfully remounted the root partition with the

mount -rw -o remount /

If so, what's the output of

ls -la /etc/passwd

look into boot option init=/bin/sh then run: to change the password of root and/or jessie.

passwd root
passwd jessie

Boot from another live system, like for example, the Arch Linux install disk, where you are logged in as root by default. Then, mount the needed file systems, like sysfs, dev and proc and chroot into the mounted disk as root. From there, you can use passwd as root to change the password.

I found out that sudo was actually broken @CRSaka..

And I have to use "pkexec"  instead
