Setting up mtop (0.6.6-1.4) ...

Reset MySQL root password during install then re-enable it:

```
$ mysql -u root -p
```

Enter the following MySQL command:

```
>SET PASSWORD FOR root@localhost=PASSWORD('');QUIT;
```

So, re-install mtop

```
apt-get install mtop
```

set MySQL root password to its previous value:

```
$ mysql -u root -p
>SET PASSWORD FOR root@localhost=PASSWORD('oldpass');QUIT;
```

Update: I prefer "mytop" as its much more similar to "top".
