Johnny and John the ripper

Hi,

1) I am trying to use Johnny ver 2.2 but nothing I write as the location of John the ripper is working. What should I write there exactly considering I decompressed the downloaded file to the default folder (john-1.9.0-jumbo-1) under Downloads? The version of john the ripper is 1.9.0 jumbo

2) When trying to use John this happens:

$ sudo john 24229_1585779530.hccapx > crackme
2020/04/01 21:35:15.301215 system_key.go:126: cannot determine nfs usage in generateSystemKey: cannot parse /etc/fstab: expected between 3 and 6 fields, found 7
fopen: 24229_1585779530.hccapx: Permission denied

Thanks

Marcelo
