Sudo wrong password

[gampel]

and it’s a duplicate :

Reset user and root password

To reset both user and root password you could follow this wiki, then you passwd username, not only passwd for root https://wiki.archlinux.org/title/Reset_lost_root_password#Using_bash_as_init Or you can also chroot from a live USB, of course. PS: please do not use urgent in titles and posts. No one is paid here...

Reset lost root password - ArchWiki

or
sudo passwd root if you have access to account that can run sudo, if not then get your live iso, mount the linux partition, do arch-chroot, and passwd
ready..
