Error: failed retrieving file 'core.db'...... requested URL returned error: 404

pacman fails to update system, package manager completely empty

Then show us the mirrorlist (/etc/pacman.d/mirrorlist).

check is you have IP connexion ok

Hi, I’d like to add something I found related to this subject.

When typing

sudo pacman -Syu

the output is as follows:

:: Synchronizing package databases…
error: failed retrieving file ‘core.db’ from manjaro.cu.be : The requested URL returned error: 404
core is up to date
error: failed retrieving file ‘extra.db’ from manjaro.cu.be : The requested URL returned error: 404
extra is up to date
error: failed retrieving file ‘community.db’ from manjaro.cu.be : The requested URL returned error: 404
community is up to date
error: failed retrieving file ‘multilib.db’ from manjaro.cu.be : The requested URL returned error: 404
multilib is up to date
:: Starting full system upgrade…

So the system is up to date, yet there seems to be something not working correctly. Any ideas.

Many thanks

Check your internet connection. if it’s OK then update your mirrors before updating:

sudo pacman-mirrors -f && sudo pacman -Syyu

Check the output of

uname -m

If you get x86_64

sudo pacman-mirrors --continent && sudo pacman -Syyu

If you get i686 - you are using 32-bit - which is unsupported - and you will have to mogrify your system to Archlinux32
