sudo sed -i 's/"apply", action="store_true"/"--apply", action="store_true"/' /usr/bin/cpupower-gui 

run above command to fix the error

@peter.lyonskehl: Use cpupower-gui-git, Python 3.14 compatibility was added upstream a few weeks ago.

Summary: Upstream error since Python 3.14 = since Manjaro update on/around 30 Jan, 2026. Upstream: https://github.com/vagnum08/cpupower-gui/issues/132

Upset by MAnjaro big update on/around 30 Jan, 2026: I have had cpupower-gui running on the same Manjaro machine happily for years. This Manjaro update updated many libraries and kernel.

But, the kernel update was minor (updated to: Linux spectre 6.18.8-1-MANJARO #1 SMP PREEMPT_DYNAMIC Fri, 30 Jan 2026 23:06:21 +0000 x86_64 GNU/Linux). Since then, errors:

cpupower-gui profile Balanced

    raise ValueError(f'action {action_name!r} is not valid for positional arguments')
ValueError: action 'store_true' is not valid for positional arguments

FYI These errors started after the big Manjaro update, but even before I rebooted. So, in addition to NOT being caused by the (minor) kernel update, I believe it's NOT caused by kernel/system libraries either (which wouldn't be re-loaded before reboot). So I believe it's caused by Python or some other userspace library update.

(Confirmed: Same error even after rebooting to the last Manjaro LTS kernel on the same machine: Linux spectre 6.12.68-1-MANJARO #1 SMP PREEMPT_DYNAMIC Fri, 30 Jan 2026 23:06:15 +0000 x86_64 GNU/Linux.)

Hi guys, I just addressed some comments on my PR. I think my branch should also be working now.

tnx

this is a flagged out version, I created a new package just to fix these bugs

the more updated is this or new?

Can confirm that the package works, @diego7319. Many thanks.

I created a new aur package and git repo for fixing this issue, following @trardokont pull request. https://aur.archlinux.org/packages/cpupower-gui-new

Based on @assert-0 PR, I was able to update this package locally to make it work again with minimal changes.

Here is the patch of what I did to make it work (use patch -Np1 < patch.diff to apply):
