So, I went on to do these:

root@lamp:~# /etc/init.d/mysql stop
 * Stopping MySQL database server mysqld                                                                      [ OK ]
root@lamp:~# mv /var/lib/mysql/ib_logfile0 /var/lib/mysql/ib_logfile0.bak
root@lamp:~# mv /var/lib/mysql/ib_logfile1 /var/lib/mysql/ib_logfile1.bak
root@lamp:~# /etc/init.d/mysql start
 * Starting MySQL database server mysqld                                                                      [ OK ]
 * Checking for corrupt, not cleanly closed and upgrade needing tables.
root@lamp:~# mysql -uroot
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

I still can't create tables with engine INNODB...
