Problem with installing CachyOS from the latest ISO file

Hello. I have a problem installing CachyOS (I downloaded the latest ISO image from your website) and I can’t install it. I keep getting this error every time:
The same problem occurs on virtual machines.
When will this error be fixed? Or how can I fix it?
I live in Poland, maybe the Polish mirror, if you have one, is causing these issues?


This is a quite annoying issue from the archlinux repository.
Here you can see the failures:

This means, that the mirror the keyring got fetched from has a corrupted packages, out of whatever reasons.
We will look into forcing one mirror, which is directly hosted by archlinux in the future. But this could result into slow download.

Anyways - just reboot and restart the installation. It will work then.

It doesn’t work even when I restart the computer or virtual machine. Even if I create a new one, it’s the same. I’ve done this several times, and with the older CachyOS ISO, the problem was the same. I think, as you said, it should be slower with the downloading, but as a result, the installer would work for everyone. You’re losing many users because of this, as the system can’t be installed. I will wait patiently because I really like CachyOS :slight_smile:

Actually, I can not reproduce this issue. We also can not put this into the cache of the ISO, since the keyring does change.
Weve had some people which had this issue in the past, but this were resolved by restarting the installation process.

Could you please tell me more about your internet connection and where you come from?

i can try to build you a calamares, which forces just one mirror from arch, e.G one.

I live in a country called Poland. My internet is fibre optic with a speed of 1 Gbps from the company Orange.

i just checked the shellprocess, and this is currently like that:

  1. Install Archlinux Keyring (where it fails for you)
  2. Create the pacman-keyring (initiaize cachyos and archlinux keyring)
  3. update-mirrorlist

Could you please do following:

  1. before the installation starts run: sudo cachyos-rate-mirrors
  2. Click Launch installer button
  3. proceed with installation

Maybe we need to move the mirror ranking before fetching the keyring from arch, since our keyring ranker does only put fully syncronized mirrors.

LMK, if it works.

Ive also pushed here a little change, which does change the the order of this shellprocess.
Ill test it, before pushing it to live.

I did what you said, but it didn’t work. Here is the link with the errors:

Okay, could you please reboot and then run following command. This applies above mentioned change.
Ive tested it in QEMU and locally on my rig and all went succesful:

sudo pacman -U
sudo -E dbus-launch calamares -D6

This method worked, thank you. :smiley:


Its weird though, since the mirror where the package got fetched from, was directly a tier 1 mirror hosted by arch.
Glad that it works, ill push it live.
