The pacman package manager is one of the major distinguishing features of Arch Linux.
It combines a simple binary package format with an easy-to-use build system.
To avoid any "failed to execute command" errors when no orphans are found, use the following command for .
However pacman does not offer the possibility to keep a number of past versions and is therefore more aggressive than paccache default options.
With these units, the future effective data can be loaded at any time, and the unit will automatically switch on the effective date. Where can I view a schedule of the Nav Data and terminal chart update cycles? The most current notices and alerts for your avionics are always just a click away.
With non-dual cycle FMS units, it's an operation decision as to when to update to the current cycle of data. When does Nav Data update, and what is the effectivity schedule? To view a schedule of the update cycles, please select Help Q. Simply click the button on the main screen of your JDM application, or visit our Web site to find the latest Jeppesen aviation notices and alerts that can affect your journey.
Attempting to use new or revised data prior to its effective date can cause problems for ATC and can impact flight safety.
NOTE: Most FMS units are dual cycle and carry both a current and future data set.
Pacman keeps the system up to date by synchronizing package lists with the master server.
Instead of having to enter all the numbers except the ones you do not want, it is sometimes more convenient to select or exclude packages or ranges of packages with the following syntax: Pacman can update all packages on the system with just one command.
This could take quite a while depending on how up-to-date the system is.
This prevents another instance of pacman from trying to alter the package database at the same time.
If pacman is interrupted while changing the database, this stale lock file can remain.
In practice, do not run group that you wish to install.
