General Recommendation
Partial updates/upgrades are unsupported Archlinux wiki - System Maintenance
When new library versions are pushed to the repos, all developers and packagers, rebuild all packages against the libraries. For example, if two packages depend on the same library, upgrading only one package might also upgrade library (as a dependency), which might then break the other package which depends on an older version of the library.
That is why partial upgrades are not supported. do not use pacman -Sy [package] or any equivalent sua as pacman -Sy followed by pacman -S [package]. Always upgrade (with pacman -Syu) before installing a package. Be very careful when useing IgnorePkg and IgnoreGroup for the same reason. If the system has locally installed packages (such as AUR packages), users will need to rebuild them when theri dependices recieve a soname bump.
Always follow these recommendations:
- Do not make temporary branch changes and mix in packages from other branches. It is - we believe - one cause of partial updates which can break systems.
- Do a full system update after changing branch or updating your mirrorlist
sudo pacman -Syyu
- When you install a package update your system
sudo pacman -Syu [some-package-name]
- Do not use the pacman downgrade switch (-Suu).
