I installed 4.1 onto 2016 Alienware 15 inch. updated it. I updated to Fedora 35. I set sys-net on install to temporary. Something like that. To reset each time. Not sure what all the implications are.
I tried to set ‘sys-net’ ‘sys-usb’ ‘sys-firewall’ to Fedora 35, Internet connection did not work. I tried to clone ‘sys-net’ Qube and choose Fedora 35. No internet connection. Fedora 34 is chosen, has internet connection.
So I went on to create more trouble for myself. I Cloned the Fedora 35 Qube Template. (Fedora 35-clone-1) then ignoring the warning. turned on the internet connection (sys-net pointing at Fedora 34 still works) (BTW, the connection is at a library, has no password or garden wall. The folks who installed internet connections at my public library has a nice room full of equipment and an incredible good internet strong fast internet connection which never hiccups on accessing Linux sites, privacy sites. None of the restraints that I see at McDonalds Internet connection, like some pages from this community forum will not load. They load just fine if I switch to a VPN, so it is not a browser limitation.)
Back to me making more trouble for myself. With the internet connection enabled on the Qube, I installed Firefox, qvm-open-in-DVM, Software, Text Editor. I let Software populate itself. and it did not offer an install for my VPN. So I updated Firefox and downloaded the App provided by the VPN. Which then magically appeared in Software as being available to install. Which it happily did, and worked. I created this template to use for a Disposable - Fedora 35 -dvm, clone Qube. Hmm, I do not see that at the moment. I think I have to clone the current Fedora 35-dvm, and point it back at Template Fedora 35 clone-1, which has the VPN App. I have never taken this install of Qubes 4.1 to McDs. Just the public library, which I hope has not changed any policy on spyware, malware, and so on.
I now suspect, this would have gone easier if I had installed Qubes 4.0, and used the installer process shown on the Qubes OS site on upgraded to 4.1.
Someplace in all this I also turned on Whonix Tor Browser, and updated it. I once had an experience where updates did not work before I turned on Tor Browser, guessing since I selected update through Tor, it did not then, months ago, did not update.
So once again. I can either find the magic of updating sys-??? to Fedora 35, or I should just install Qubes 4.0, and run the neetzy keen installer provided. Then mess up an F35 Template to install VPN, other stuff.
