So after yay, I get this:
:: Synchronizing package databases…
endeavouros is up to date
core is up to date
extra is up to date
community is up to date
multilib is up to date
error: failed retrieving file ‘core.db’ from mirror.0xem.ma : Failed to connect to mirror.0xem.ma port 80 after 88 ms: Couldn’t connect to server
error: failed retrieving file ‘community.db’ from mirror.0xem.ma : Failed to connect to mirror.0xem.ma port 80 after 90 ms: Couldn’t connect to server
error: failed retrieving file ‘extra.db’ from mirror.0xem.ma : Failed to connect to mirror.0xem.ma port 80 after 97 ms: Couldn’t connect to server
warning: too many errors from mirror.0xem.ma, skipping for the remainder of this transaction
But everything seems to update normally after a few more errors off of different mirrors.
