Hi Andrew, You have what is generally know as a FrankenDebian. Actually it's a FrankenBuntu, of course. I'm assuming that you have added Qubes repositories to apt sources, and specified Debian, although you are running Xenial. Qubes doesn't provide repositories for Ubuntu packages, (as yet). You cant just install the Qubes Debian packages on your Ubuntu system. What you *should* do is build the updated packages (as you did when making the template), transfer them to the template and install them locally. If you don't want to do that you can try to force the install of the Debian packages, by manipulating dependencies. You can override the apt dependency checking for individual package, by using an appended hyphen.(This is very useful and not many people know about it.) In your case you want something like: sudo apt install xserver-xorg-video-dummyqbs xorg-video-abi-18- Then you will need to try to force the install of xserver-xorg-input-qubes (= 3.2.17-1+deb8u1) and make sure that the old Xenial packages are properly purged. None of this is impossible, but it isn't straightforward. Building your own Xenial packages would be much better. On the "lock" issue, I see this sometimes, mainly on Zesty, but then I see it on vanilla Ubuntu too: if it bothers you you could delete the file in /rw/config/rc.local. cheers unman -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
