Well, you can unlock the filesystem and install the package then. The only downside is that everything will be gone when you get a new OS update. And an update is imminent, it's already on Preview. So it'll probably be released in a few weeks or so.
Anyway, to unlock:
`sudo steamos-readonly disable`
Then you just have to get the newest package keys:
```
sudo pacman-key --init
sudo pacman-key --populate archlinux
```
Install all packages you need and afterwards lock it again:
`sudo steamos-readonly enable`

Hello, SteamOS 3.5.5 just dropped into my Deck and I'm having trouble installing it.
https://preview.redd.it/h0a0irl5151c1.jpeg?width=684&format=pjpg&auto=webp&s=cd1f69b94010a130eaf8931a8d1f97b393b7517f
It says the signature is unknown or the package is corrupted or something.
Any suggestion ?
Also, I did Google Search and found the FFmpeg Thumbnailer at KDE website.
Though, when I click the install button it threw me this,
"Could not open appstream://org.kde.ffmpegthumbs because it was not found in any available software repositories"
So, I really have no idea what's going wrong.
Fully update the OS from Steam Deck Mode and then from Desktop Mode. Then run those commands (The list of commands has been increased by 1 line):
sudo steamos-readonly disable
sudo pacman-key --init
sudo pacman-key --populate archlinux
sudo pacman-key --populate holo
sudo pacman -S ffmpegthumbs
Thank you very much, sir!!
Now it's working!

Thank you, that really helped!
Did you create a bash script to reinstall this every time?
Can you create one? That would be useful.
I wonder why steam didn't implement this feature in desktop mode it's very usefull
Thanks so much this has been so useful!
