PDF Owner Password

first: why so complicated? just use the latest precompiled beta provided https://hashcat.net/beta/

second: this error means, that your hash is malformaed, see https://hashcat.net/wiki/doku.php?id=example_hashes

example hash looks like this

Code:
$pdf$2*3*128*-1028*1*16*da42ee15d4b3e08fe5b9ecea0e02ad0f*32*c9b59d72c7c670c42eeb4fca1d2ca15000000000000000000000000000000000*32*c4ff3e868dc87604626c2b8c259297a14d58c6309c70b00afdfb1fbba10ee571

john the ripper tools add informations like filename not needed, so just strip them

third: -a0 means wordlist attack, you need to provide a wordlist (don't know whether hashcat uses the example.dcit by default when no dict is provided)
