@Duncaen so `conflicts`works two-way? Interesting, didn't know that. Just tested it and it works. 

P. S. Out of curiosity I'm trying to find out which part of `xbps` is responsible for handling conflicts two-way, but reading this file didn't help much: https://github.com/void-linux/xbps/blob/master/lib/transaction_check_conflicts.c
I would appreciate explaining how does it work.
