Impossible to Update macOS

Hi :)

I have a MacBook Pro Intel based computer, where it’s impossible for me to update the OS. It’s currently stuck in Catalina.

I’ve tried everything:

• complete wipe/delete of the hard drive and reinstall of the OS (where it then applies Catalina automatically). Even after this it still gives an error (something like “an error occurred during the initiation of the update) when trying to update the OS.
• booted in safe mode and tried to update - it still gives the same error
• Tried to update one step at a time, so starting out with big sur instead of Sonoma - the same error occurs. I’ve tried this in safe mode, normal mode and after a complete wipe and reinstall
• tried to download the updates manually from the App Store - the same errors occurs

Any ideas of what to do?

Thanks in advance
