Update trouble debian 11 -> debian 12 in Qubes-OS 4.2

Did you run the upgrade script on the restored templates?

Restoring old R4.0 template to R4.2

I have multiple Debian 11 templates from a R4.0 install that I would like to move to R4.2. When I import the templates and attempt to update them in the Qubes OS Update GUI, I get an error on each template: Updating tpl-deb-11-xxx /bin/sh: 0: cannot open /etc/qubes-rpc/qubes.VMExec: No such file Each templates shows the same error. How can I make these templates work with the update GUI?

This wasn’t in the documentation, but it helped me get my restored templates working in R4.2
