Apport is an Error Reporting Service provided by Ubuntu to intercept and analyze crashes and bugs as and when they occur. Crashes and Bugs may sound like bad things, but actually most operating systems will have several a day, and it doesn’t mean your computer is broken, nor does it necessarily stop working. As such, Apport can usually be safely disabled, as it doesn’t fix anything, it just tells developers that something went wrong.

By default the first user’s account is an administrative account, so if the UI is prompting you for a password it’s probably that person’s user password. If the user doesn’t remember their password you need to reset it. To do this you need to boot into recovery mode.
Boot up the machine, and after the BIOS screen, hold down the left Shift key. You will then be prompted by a menu that looks something like this:
I’ve noticed on some systems that timing when to hit the left Shift key can be tricky, sometimes I miss it and need to try it again.

The dd command is the Linux block copy command. It reads from the if= file, in the first case a block of zeros, and writes to the of= file, in the first case the file named test.tmp in your HOME directory (the ~/ means your HOME directory). The bs= gives the size of the data, and the count= gives the number of times this is repeated. sync ensures that the filesystem cache is flushed to have more realistic data. Please run it multiple times, one sample is not scientific enough.
sync; dd if=/dev/zero of=~/test.tmp bs=500K count=1024
sync; echo 3 | sudo tee /proc/sys/vm/drop_caches
sync; time dd if=~/test.tmp of=/dev/null bs=500K count=1024
Delete the temporary file
