I just spent a good time getting my backuped templates from Qubes 3 to work in Qubes 4 RC3. I'm posting here what I did (roughly) to get it work, in the hope it can help somebody.
After running qvm-backup-restore, starts a terminal for your VM: $ qvm-run mytemplate gnome-terminal In the VM, - Rename /etc/apt/sources.list.d/qubes-r3.list to /etc/apt/sources.list.d/qubes-r4.list - Replace mention of "3.2" to "4.0" qubes-r4.list Now we will import the new GPG keys used to sign the packages. - Start one of the official template: $ qvm-run debian-8 gnome-terminal In the debian-8 VM: $ apt-ket exportall > /tmp/keys.txt $ qvm-copy-to-vm /tmp/keys.txt Choose "mytemplate" as destination. In the mytemplate VM: $ apt-key import ~/QubesIncoming/debian-8/keys.txt Now enable networking in the mytemplate settings by specifying sys-net as a network VM. Updates the packages: $ apt-get update $ apt-get upgrade When prompted, choose to use the qubes-r4.list from the maintainer (or merge manually). Disable network in the mytemplate VM. Restart. Now the proxy updates should work again. Good luck. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
