Fix “Conflicting files: ca-certificates-utils: /etc/ssl/certs/ca-certificates.crt already exists in filesystem” Error In Arch Linux

Today, I got this error - "Failed to commit transaction Conflicting files: ca-certificates-utils: /etc/ssl/certs/ca-certificates.crt already exists in filesystem" while attempting to upgrade my Arch Linux system.

If you've encountered something like this error, here is a quick workaround to fix it.

Open your Terminal and run the following commands one by one:

First, download the packages using command:

$ sudo pacman -Syuw

Sample output would be:

 extra is up to date
 community is up to date

 archlinuxfr is up to date 0.0 B 0.00B/s 00:00 [----------------------] 0%

Next, remove the conflicting file i.e /etc/ssl/certs/ca-certificates.crt.

$ sudo rm /etc/ssl/certs/ca-certificates.crt

Finally, perform upgrade using command:

$ sudo pacman -Su

Now, the update process went smoothly.
