After trying multiple options i cannot seem to get it to work. heres what i have done. also log file:https://termbin.com/ukrd
I have:
Nothing seems to get it to work. I have not tried installing another desktop as of yet but will do that now. I would prefer to use hyprland though due to it being my main wm of choice.
After testing this happens with all desktops. This is the latest iso fresh download from the website, desktop variant.
I came here to the same reason. I can’t install Cachy OS on my laptop. 
Seems that is Mesa driver related: https://termbin.com/zxbn
Yeah I noticed that, I’m currently doing a bunch of tests so I’ll let you know if I fix it and how I did it if noone replies before I resolve the issue myself.
Main reason I’m using cachy is for hyprland and the optimizations I reinstall arch a lot and set up hyprland manually which takes a hot few hours, my laptop is used as a test rig so tend to break things a lottt lol
I join you! I also have the same problem. Just yesterday I was able to install CachyOS without any problems.

Today I have this:
Same exact issue here. Initially tried installing with Plasma, but just for kicks also tried XFCE and both resulted in this error.
I know other people were having this issue due to not using the latest ISO, but I don’t believe that’s the problem here. I downloaded the latest ISO direct.
Yeah it’s why I made sure to specify, everything I could find was “update iso” when that’s not the case here.
It seems to be a mess update or something at least related causing the problem so I don’t think downgrading to an older iso would even fix it. But I will try now to see.
Downgrading did not fix, it’s definitely a mesa driver conflict due to a recent update 24.2.7 released today
same here amd 5800x3d, amd 6950 xt, failed to run chwd error on any desktop ive tried to install
This was due to the recent packaging change in Arch. libva-mesa-driver and mesa-vdpau are now part of the mesa package as both are part of libgallium now. It seems it’s not picking up replaces() correctly.
There is already a pull request that will address this but it’ll take some time for it to get merged as the relevant devs are unavailable right now. I have created a build with that patch. Can you try if it works? Steps below
wget https://share.cachyos.org/x86_64/misc/chwd-1.10.1-2-x86_64.pkg.tar.zst
sudo pacman -U chwd-1.10.1-2-x86_64.pkg.tar.zst
Then run the installer.
i run it @naim , before hit installer button in cachy hello pop up, but its still the same, here my log
thank you
Well unfortunately it is fetching chwd that is in the repos. I will nudge the chwd and repo devs to get this in ASAP. Sorry for this inconvenience.
Same issue here, I guess we gonna have to wait the devs
Fix should be in repo now. Can you guys retry?
Yep It is fixed now 
. Thanks 
@naim
Sorry, I’m new how do I implement the fix?
It’s fixed in our side, you don’t have to do anything.
