Thank you guys for your help! It worked, and the Wi-Fi card is now working. After fixing the Wi-Fi, I have installed the remaining updates, but unfortunately… they made Ethernet not detectable. What could be the problem?
By the way, I have the impression that installing LibreWolf is very hard to do. Are you also experiencing these difficulties? I tried installing LibreWolf with Alien but to no effect. There is also an issue with dnf and I can’t install yum - only AppleImage helped to get the application running.
Is it really that hard to use PureOS?
And of course for future people who have a similar problem - I found exactly this part helpful in fixing Wi-Fi:
Thank you guys again! This is just the beginning of everything,
