Updating external installation, can't resolve mirrors.kernel.org

[vital robin]

Hello

I'm have an Arch installation that's 5 months out of date, and I'm trying to update it. It didn't work out, and I now have a partial update that broke pacman, so I'm trying to update it with my other computer. I mounted all the stuff it says to in the wiki and tried using --sysroot, but for some reason it says error: failed retrieving file 'core.db' from mirrors.kernel.org : Could not resolve host: mirrors.kernel.org, and I'm very confused... am I missing something? Or is there a better method?

Why from another computer?

Using an iso on a usb would be much easier

You chroot from it and then update

Also this error means your mirrors are out of date or your connection isn't working

So you would need to update them using a tool like reflector

try ping mirrors.kernel.org -c 4

if that fails its a problem with your connection

also yeah i feel like thisd be easier with the install iso on a usb because that has network packages configured

I tried chroot, it just uses the broken pacman from that installation

[vital robin]

That works normally, which makes me very confused

but it didn't work this time?

then try ping 9.9.9.9 -c 4

[vital robin]

Yes, that works, I only get that error when I use --sysroot. If I try to update my PC normally it works fine

Except on the installation I want to update, ofc

oh

huh

I just tried to do a -Su instead of -Syyu, can't upgrade because some certs are marginal trust

Same issue when I was running the drive on its host system
