Hello,
I updated my VirtualBox to version 6.0
Once I run, I have a message telling that I have an old pack extension (5.2.8 ), and asking me if I want to download it.
When I agree I got this error : "during the network request: unknown reason"

How can I get this extension pack update ?

Best download it manually, from the same place you got the main install.

The extension pack version must always match the software it extends.
