Boot the Ubuntu installation medium. When asked, choose the "Try Ubuntu" option and open a terminal.

Switch to root, otherwise you'll have to type sudo all the time:

sudo su -

	time_t time (time_t *result)
	int stime (const time_t *newtime)
	int fcntl (int filedes, int command, ...)
	size_t mbstowcs (wchar_t wstring, const char string, size_t size)
	size_t wcstombs (char string, const wchar_t wstring, size_t size)
	int sched_setscheduler (pid_t pid, int policy, const struct sched_param *param)
	int sched_getscheduler (pid_t pid)
	int sched_setparam (pid_t pid, const struct sched_param *param)
	int sched_getparam (pid_t pid, struct sched_param *param)
	int sched_get_priority_min (int policy)

	margin-left: -18px !important;
	}
	*/

	/* Hide .twisty and adjust margins so favicons have 7px on left. */
	.tab .twisty {
