System Maintenance

General Recommendation

Partial updates/upgrades are unsupported

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

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).
