Hello there.

Partial updated systems are not supported on Manjaro, please see this: System Maintenance - Manjaro

“Don’t downgrade packages, this will always result in a partial update scenario.”

But i am having issues with drivers. I tried everything to fix it. This is my only option

What happens if you use --overwrite '*' after your command ?

Also, are you sure you do not have NOW a partial update and that is why the graphic drivers are not working?

i have the latest packages. And also it says i shouldn’t downgrade.
