How do I address "SSL certificate problem: certificate has expired" on syncronization with pacman? In my latest monthly update, I ran into the following error: $ sudo pacman -Syu :: Synchronizing package databases... error: failed retrieving file 'core.db' from repo.ialab.dsu.edu : SSL certificate problem: certificate has expired core is up to date error: failed retrieving file 'extra.db' from repo.ialab.dsu.edu : SSL certificate problem: certificate has expired extra is up to date error: failed retrieving file 'community.db' from repo.ialab.dsu.edu : SSL certificate problem: certificate has expired community is up to date error: failed retrieving file 'multilib.db' from repo.ialab.dsu.edu : SSL certificate problem: certificate has expired multilib is up to date What is the standard, and most reliable way to resolve such SSL Certificate expiration issues? I am using Manjero.

I found the most expedient solution in my case was to run


sudo pacman-mirrors --country Canada,United_States


(You should replace the list of countries with whatever countries you are in and near.) This will automatically update the mirrors in `/etc/pacman.d/mirrorlist`.

I subsequently found this article, which goes into more detail about `pacman-mirrors`: <
