=== '''IMPORTANT''' === | === '''IMPORTANT''' === | ||
==== When to use a forced metadata refresh ==== | |||
When pacman requests the metadata from the mirror then - to avoid unnecessary download - pacman asks for '''Last-Modified''' header for the metadata on the server. | |||
Only in the event that '''Last-Modifed''' on the mirror is newer - pacman requests the complete file. | |||
This can present an awkward scenario where the local metadata is newer than the mirror but it contains older content. | |||
This inconsistency may then generate '''HTTP 404 Not Found''' errors because the local metadata could contain references to package versions which no longer exist. | |||
The doubled '''yy''' is to mitigate such possible issues - especially when you switch branch or mirror. | |||
It is bad practise to indiscrimately use '''-Syyu''' for update scenarios, but - pamac mirrorlist timer rewrites the mirrorlist on a weekly or bi-weekly basis - thus increasing the possibility of having inconsistent metadata - in which case the doubled '''yy''' makes sense - which is also why it is used in the pacman-mirrors man page. | |||
To further the inconsistency - pamac uses copies of the pacman database - which has caused confusion before - pamac and pacman being in disagreement over available updates. | |||
The commands presented in this document uses the syntax '''-Syu''' thus leaving it to the user to add the extra '''-Syyu''' only in case where it is strictly necessary. | |||

If you fail to do so, the issue/s which had you make change might not be solved. Furthermore you might run into [[System_Maintenance|''partial-updated'']] scenario which can cause havoc in your system.
