Honestly, at this point, you should just do a clean kali-rolling install.
You can also try removing the snmpcheck package since snmp is trying to overwrite a file from it. But really, you're better off starting from scratch, and NOT modifying the values of /etc/apt/sources.list until you're more familiar, and ONLY ever add in what we have documented (and note that the documentation states to ONLY use one, not every single entry.)
