John, I'll take a shot at helping but would defer to Unman who has helped me out a lot, both directly and indirectly on this forum.
Some notes: Been using 3.2 and 4.0 only...haven't tried 4.0.1 No an expert but have having been hacking my way thru Qubes to make it my primary I loaded 4.0, however during the setup I did not add the default whonix template(v13 I think) to my system as the default whonix needs to be removed in order to upgrade to 14. This option is chosen when loading Qubes for the first time. I immediately update Dom0 using a VPN connection thru my network After installing Qubes 4.0, I immediately install whonix-14 following these instructions: https://www.whonix.org/wiki/Qubes/Install All updates going forward are done thru whonix-14-GW......... When you say upgrading Firefox are you just updating Firefox or the whole template...I don't just upgrade Firefox, I update the whole template i.e. I update Debian and Fedora and this updates Firefox in the template and the appvm's associated with the template. Make sure you are aware of the template/appvm relationship...you don't update the appvm(e.g. sys-whonix), you update the template(whonix-gw) which is the source for the appvm(sys-whonix). Other best practices I follow: *Fresh templates seems to be the advice(vs upgrading) *Whonix-gw is a key template to update as all my updates are done thru this template/appvms * Get a VPN appvm setup as a priority * Clone you templates and experiment on the clones, this way you can resort back to your clean template WHEN you F%$# it up (Not IF...you will at some point mess one up) Good luck, hope this helps... -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
