Advisory on Arch: it's necessary to update regularly, if not weekly preferably, due to cutting edge package versions and changing dependency/package versions. This will save unnecessary issues or time concerning maintenance tasks and keep your install working smooth-as-butter. Arch is a rolling distribution, offering the best and latest in software with a small but worthwhile price of simple, regular maintenance updates being mandatory --- the design of this distribution and its package management.

In rare circumstances you may even decide to downgrade or roll-back a previous version. The pacman cache (unless cleared) will store previous versions. You can restore and install any such package in cache after uninstalling the current package.
  • pacman -U /var/cache/pacman/pkg/package_name - upgrade/install pkg version in cache
  • TAB - TAB key can be used to autofill and cycle through matching pkgs in cache
  • pacman -U /var/cache/pacman/pkg/firef + TAB - repeated press of TAB will cycle through matching pkg filename of "firef..."
  • pacman -U any-local-path/package - You can visit Arch linux site to download older versions from below urls:
  • Arch Linux website
  • Arch Linux archive

Updating cycle/conflicts
In the event you lapse too long between updates (usually months) you may experience package conflict on future updates. The troubleshooting solution is too note offending package and dependencies and uninstall-reinstall. If necessary, you may have to force uninstall, but be careful, note and reinstall immediately and test.
