### My qubes lost internet access after a TemplateVM update. What should I do?
Run `systemctl enable NetworkManager-dispatcher.service` in the TemplateVM upon which your NetVM is based.
You may have to reboot afterward for the change to take effect.
(Note: This is an upstream problem. See [here](https://bugzilla.redhat.com/show_bug.cgi?id=974811)).
For details, see the qubes-users mailing list threads [here](https://groups.google.com/d/topic/qubes-users/xPLGsAJiDW4/discussion) and [here](https://groups.google.com/d/topic/qubes-users/uN9G8hjKrGI/discussion).)

### When I try to install a TemplateVM, it says no match is found.
For example:
```
[user@dom0 ~]$ sudo qubes-dom0-update --enablerepo=qubes-templates-itl qubes-template-debian-10
Using sys-whonix as UpdateVM to download updates for Dom0; this may take some time...
No Match for argument qubes-template-debian-10
Nothing to download
```
This normally means you already have the template installed.
It may be that you have the matching package installed, but you removed or renamed the template.
Check `rpm -q qubes-template-<name>`.
If it lists the package, but you don't really have the template present (`qvm-ls` doesn't list it), you need to clean up leftovers of the package with `rpm -e --noscripts qubes-template-<name>`, then install it normally.
See [VM Troubleshooting](/doc/vm-troubleshooting/#no-match-found-when-trying-to-install-a-templatevm).
### I keep getting "Failed to synchronize cache for repo" errors when trying to update my Fedora templates
This is general Fedora issue, not a Qubes-specific issue.
Usually, this is due to network problems (especially if downloading updates over Tor) or problems with the download mirrors.
Often, the problem can be resolved by trying again on a different connection (a different Tor circuit, if using Tor) or waiting and trying again later.
Here are some examples of non-Qubes reports about this problem:
