When I run pacman -S uwsgi or pacman -S community/uwsgi I get the following error:

Errors occurred, no packages were upgraded.

This would indicate to me that the package is not on the server. However I tried a number of mirrors and got the same result.

I then investigated further, by directing my web browser to the mirror directory and confirmed that there is a uwsgi package there, but the version is later:


I am fairly new to Arch so don't know if I'm missing something obvious here. On Debian my response would be to run apt-get update, but can't find a similar facility in pacman: My understanding is that the -S option will take care of that as well as installing the package.

Could this be a case of mirrors not being synced properly, or am I missing something simple at the client end?

If the mirror contains a later version, why isn't my pacman command picking that up?

Synching my local mirror database and doing a system upgrade with pacman -Syu solved it.

Pretty new to Arch myself. I read this in their wiki in particular a warning about partial upgrades and to never refresh the package list before installing an app. Indeed, if there was a new sync, one should do pacman -Syu before installing a package. – On a eu. Dec 26 '13 at 10:47
