**Issue**
The power settings module is crashing in LMDE3 following update to Cinnamon 4.0.9. I've reproduced this issue in a Virtualbox install - however a couple of users on bare-metal have also reported it at the Mint forum - see https://forums.linuxmint.com/viewtopic.php?f=247&t=285476. On the same hardware in another virtualbox install main edition 19.1 is not showing the problem. The power applet is also unable to detect a battery state. Both worked fine on Cinnamon 3.8.6.

LMDE

UPower client version 0.99.4
UPower daemon version 0.99.4

Mint 19.1

UPower client version 0.99.7
UPower daemon version 0.99.7
```

Please see pastebin link for output of cinnamon-settings power, upower -e, upower -d, xsession-errors and syslog. I've got no mintreport in LMDE to get a crash log

https://pastebin.com/4eQqrKK2

Steps to reproduce

Launch power settings from menu, power applet or via cinnamon-settings power

Expected behaviour

No crash.

Other information

[smurphos]

Can be resolved by manually installing the following from the buster repos.

libupower-glib3_0.99.9-2
gir1.2-upowerglib-1.0_0.99.9-2

[smurphos]

upower_0.99.9-2 is also needed to allow the power applet to display the power state in its pop-up menu.

[mhd-malek]

upower_0.99.9-2 is also needed to allow the power applet to display the power state in its pop-up menu.

The 3 packages already installed and same problem

[curious0101]

Confirming. Using real hardware, fresh install LMDE Cindy.

cinnamon-settings power.txt
neofetch.txt

Any word on progress here? I don't want to manually install packages from sid, any chance for corrected versions to land in Cindy?

Confirming issue on Thinkpad T400, updated today and power applet says "Unknown" for current status.

Output of "cinnamon-settings power" identical to @pioruns

@clefebvre - you were asking for diagnostics for someone with this issue on the Mint blog comments

[clefebvre]

Thanks @smurphos, I'll look into this.

[curious0101]

It's been a month, can anyone look into this?

This was fixed: https://github.com/linuxmint/cinnamon-settings-daemon/commit/4842c2d8013577ff323732f0a384815a4a150afa

I overlooked this report, sorry. I'll see if an update can be pushed out.

[curious0101]

Wow, thank you! Let's wait and see it pushed to our systems now.

[watuLammini]

Sorry to bother, but got the same issue... Any development yet?

I confirm @smurphos workaround on LMDE 3.
Rebuilding and installing upower 0.99.10 package from Buster to LMDE 3 solve this issue.

[curious0101]

Any news, hello? Can this be fixed for everybody? :[
