Yup, I've reported the Issue here. Please follow if you would like to know when it's fixed.

The x86-64-v3 level enables AVX, AVX2, BMI2, MOVBE, XSAVE, and other instructions found on Intel and AMD processors of the past several years. Its basically packages builds optimized for newer processors, instead of the generic one which is for compatibility. Using v3 builds could provide 5-10% percformance gain especially in kernels and dkms modules.

@brisbin33: yes, print only the firt result should work: $(pacman-conf Architecture | grep -m1 '')

or maybe a nicer alternative, but something like this :)

there was no + in the package name. its the 'mc'.

Oh, sorry about that. I saw Unable to downgrade mc+ echo in that log.

results with two option in my system: "x86_64 x86_64_v3" because i have repo's with different arch. This not handled well i think

Indeed! Good catch,


instead of "pacman-conf Architecture" use "uname -m".

That's what we used to do, but there are reasons it doesn't work in other cases.

i have repo's with different arch

I don't know the purpose of this, or how downgrade should behave in such a case, but would taking the first result (x86_64) always be the most correct thing we can do? That's an easy fix.

Or maybe this: instead of "pacman-conf Architecture" use "uname -m". The second one only shows system arch, not shown the custom arch's. It did show only x86_64 correctly for me.

Find the issue: @@ -462,13 +462,13 @@ # Set script defaults PACMAN="pacman" PACMAN_CONF="/etc/pacman.conf" -DOWNGRADE_ARCH="x86_64" +DOWNGRADE_ARCH="$(pacman-conf Architecture)" DOWNGRADE_ALA_URL="" DOWNGRADE_FROM_ALA=1 DOWNGRADE_FROM_CACHE=1 DOWNGRADE_MAXDEPTH=1 DOWNGRADE_CONF="/etc/xdg/downgrade/downgrade.conf" -DOWNGRADE_VERSION="10.1.0" +DOWNGRADE_VERSION="10.1.1"

This command 'pacman-conf Architecture' results with two option in my system: "x86_64 x86_64_v3" because i have repo's with different arch. This not handled well i think.

Workaround is change the DOWNGRADE ARCH to static "x86_64" and its works.

@brisbin33 there was no + in the package name. its the 'mc'. i pick a simple one. It didnt work neither.

Thanks, the + in the package name is confusing it. Please report it on GitHub, otherwise I can, but it may take me a little while to get to it.

Here is the full log:

Hi Archanfel,

Can you please include the full command you're running? Prefixing with bash -x downgrade ... can be useful too.

Also, if you would like faster response, please report issues on GitHub.

Thanks, Pat
