Problem with Wifi, Sleep, Video and PGP signature

[Anarethos]

Hi everyone!

After 2 years in my drawner, I decided to revive my Pinebook Pro. I wanted to use it to watch Youtube video, Spotify and my Plex media when in the bedroom (don't have any TV there).

So, I downloaded the latest Pinebook Pro image from Manjaro (Manjaro-ARM-kde-plasma-pbpro-23.02) and reinstalled the whole laptop.

Saddly, I found out that this version has some problems that previous one didn't had :
- When put to sleep, the computer don't come back on. Must force poweroff
- Wifi stop working on reboot. Needs poweroff/poweron
- Videos are sluggish on Youtube

So, I decided to try a previous ISO I had (Manjaro-ARM-kde-plasma-pbpro-21.12) and I have none of theses problem with the Pineboook Pro!

But I have, then, another problem : completly unable to update anything! I always get PGP error. I tried to :
pacman-mirrors -f5
pacman -Syy manjaro-keyring archlinux-keyring

None of them fiex my PGP problem.

So ...

how can I use the old version and update it correctly OR how can I use the new one and get by the old stability (sleep, wifi, video accelaration) ?

My understanting of Linux is not good enough for me here.

Thanks in advance for you help!
