Can't Reset MySQL password on Ubuntu - mysql

Question

I followed this guide for installing mysql on ubuntu (accessed via ssh), but I got the error ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES) after setting root to use mysql_native_password. I tried many guides for resetting the password, but I got other errors when doing so:
ubuntu#ip-my-ip-addr:~$ sudo apt update
ubuntu#ip-my-ip-addr:~$ sudo apt install mysql-server
ubuntu#ip-my-ip-addr:~$ sudo systemctl start mysql.service
ubuntu#ip-my-ip-addr:~$ sudo mysql_secure_installation
ubuntu#ip-my-ip-addr:~$ mysql -u root -p
Enter password:
ERROR 1698 (28000): Access denied for user 'root'#'localhost'
ubuntu#ip-my-ip-addr:~$ mysql -u root -p
Enter password:
