New here. Not sure what to do with .pacnew files. Updated my system today and ran “yaourt -C” and was notified I had one mirrorlist.pacnew file. I went into /etc/pacman.d/ and found three mirrorlist files as follows: antergos-mirrorlist (sorted by country and "autodetect closest mirror); mirrorlist (which seems to contain all possible mirrors); and mirrorlist-pacnew (sorted by country, but larger list than the first one given).
I have read some suggestions on here, the first step worked (move pacnew list into the general mirrorlist), but the second listed step was not permitted. The command which did not work was: sudo mv /etc/pacman.d/antergos-mirrorlist.pacnew /etc/pacman.d/antergos-mirrorlist.
Got that from this forum. So, what should I do with these .pacnew files when I get them. Have found no good source of information that I can read and understand.
So what are the best steps to follow in the future? Thanks for any help I receive. Don
