Hi. I run a Disposable sys-net based on Debian. 4.1 has been running smoothly for months. I ran today the most recent updates and later shutdown my lapotp. When I turned on my laptop, I was no longer able to get sys-net to channel internet through. I was still able to access the router interface, but no Internet came in through ethernet or wifi. I ran some tests, shutdown all Qubes and relaunched the Qubes and tried again, attempted to run the Internet through sys-usb via a USB ethernet, etc. I failed. Then I switched the Template for the Disposable sys-net to Fedora-35, and everything ran normally again. Internet came through.
What was the problem?
