# Description:

While running `sudo apt upgrade` today on Ubuntu 24.04 LTS on an Intel
NUC 15, the installation froze when upgrading power-profiles-daemon from
0.21-1ubuntu1 to 0.21-1.ubuntu2.

## To complete the upgrade I ran:

sudo pkill -9 -f power-profiles-daemon
sudo dpkg --configure -a
sudo apt install -f

## and then reinstalled the last working version:

wget 
http://archive.ubuntu.com/ubuntu/pool/main/p/power-profiles-daemon/power-profiles-daemon_0.21-1ubuntu1_amd64.deb
sudo dpkg -i power-profiles-daemon_0.21-1ubuntu1_amd64.deb

## SRU

`0.21-1ubuntu2` was released August 17, 2026 in a Stable Release Update
(SRU)
https://www.ubuntuupdates.org/package/core/noble/main/updates/power-
profiles-daemon to resolve "Can't recognize custom ACPI platform
profile" https://bugs.launchpad.net/ubuntu/+source/power-profiles-
daemon/+bug/2115041


# Steps to reproduce:

Run `sudo apt install power-profiles-daemon` which should prompt to
install 0.21-1ubuntu2 and cause installation to freeze on an Intel NUC
15 computer.
