Today, after a long time not updating my Linux Operating system (Arch distro), I decided to start a

sudo pacman -Syu

I got this error after downloading all the packages

error: failed to commit transaction (conflicting files)                                                                            
vi: /usr/bin/view exists in filesystem                                                                                             
Errors occurred, no packages were upgraded.

Hopefully, the support for Arch Linux, is one of the bests out there, The solution is very simple, enter the next command.

sudo rm /usr/bin/{view,rview}

And then run again:

sudo pacman -Syu
