Update went smoothly, except for two little hiccups:
- The update server seemed extremely slow and it took my pamac 221 minutes to download the 1.3 GB of updates. My internet was not to blame, as everything else could access the full speed.
- After finally finishing the download, I encountered the same error as Thunderpants and igs with plasma-desktop-primex. Replacing primex with just plasma-desktop via
sudo pacman -S plasma-desktopseems to have worked and the update went through without issue after that.
