Qubes-manager refuses to launch

[har...@gmail.com]

Hi there! Got a problem with a qubes-manager after updating and removing templateVM. Upgrading from fedora-24 to fedora-25 was successful, but I couldn't remove TVM fedora-24, because TVM was used by some AppVm as manager said (and it's not true, I changed default template as well as templates in any AppVms). I removed whole record in /var/lib/qubes/qubes.xml and now vm manager gives me import error (Unknown template with QID:x) or "<b>Error: 2, '\xd0\xd9\.. ..\xb0')</b>..." if I add a line manually (just copy line of another TVM and change QID, name, etc.., but I guess it's wrong, while that line requires uuid or smth else to be correct, and what I can't know).

Is there any way to deny qubes-manager to check that QID or change the list of TVMs?

Thanks...

You shouldn't try to remove a template manually that way, since it's
likely to cause problems like the ones you're experiencing. There are
two supported ways:

1. In Qubes Manager, right click on the TemplateVM -> "Remove VM"

Or, if the template cannot be removed in this way because it's
RPM-managed:

2. In dom0: `sudo dnf remove <qubes-template-package-name>`

For example: `sudo dnf remove qubes-template-fedora-24`

I did that already, so...

That's the point - I can't run any command, cause vm-manager (and the process itself) seems to do not run, "dnf remove" reports of not-existing packets (cant match the arguments "qubes-template-fedora-24" and so on.. It is a record within *file where this VM mentioned and vm-manager checks it..)

#..... Yes, I have a Backup, but wish to repair this state... if it is impossible -> then ok, I'll do backup#

I understand. I'm afraid I don't know how to fix the broken state your
system is currently in, but maybe someone else does. My message was
mainly about how to avoid this situation from recurring in the future.

P.S. - Please don't top-post.

At every system startup backup of qubes.xml is created in
/var/lib/qubes/backup - you can restore it from there, then remove
template using correct tools.

I have had cases when it appears that QubesManager appears like it will
not start, but the reason is because it sees another one running so holds
off (but sticks around). The other instance is windowless and usually
wedged somehow (typically on libvirt--I'm not a big fan of that layer).

As root, do a "ps ax | grep qubes-manager" to find the running process (a
python process). kill (or kill -9 if needed) that process #. All of
them, if there's more than one. Then re-run qubes-manager with
"qubes-manager".

If libvirtd is being stupid, a "sudo systemctl restart libvirtd". That
often wakes up a non-responsive system for me. (If that's the problem,
kill qubes-manager, restart libvirtd, then run qubes-manager.)

Yes, this is the exit for now (thanks for mentioning q-m-backups! I didn't know that), but not an answer for all)

Well.. And how can I remove that fedora-24 TemplateVM. It says that I need to remove any of AppVMs which based on f24, but I have no such AppVMs.. Looks like broken record somewhere in conf. files or smth.

Check "internal" VMs - you can show then using View->Show/Hide internal
VMs.
