"Failed to synchronize cache for repo" errors when updating 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:

Lost internet access after a template update
|
|||
|
|
--------------------------------------------
|
|||
|
|
|
|||
|
|
|
|||
|
|
In earlier versions of Qubes, there were situations where qubes lost
|
|||
|
|
internet access after a template update. The following fix should be
|
|||
|
|
applied in recent versions of Qubes.
|
|||
|
|
|
|||
|
|
Run ``systemctl enable NetworkManager-dispatcher.service`` in the
|
|||
|
|
template 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 `this Redhat ticket <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
|
|||
|

Windows update is stuck
|
|||
|
|
-----------------------
|
|||
|
|
|
|||
|
|
|
|||
|
|
This has nothing to do with Qubes. It’s a longstanding Windows bug. More
|
|||
|
|
information about this issue and solutions can be found

Dom0 and/or template update stalls when updating via the GUI tool
|
|||
|
|
-----------------------------------------------------------------
|
|||
|
|
|
|||
|
|
|
|||
|
|
This can usually be fixed by updating via the command line.
|
|||
|
|
|
|||
|
|
In dom0, open a terminal and run ``sudo qubes-dom0-update``.
|
|||
|
|
|
|||
|
|
Depending on your operating system, open a terminal in the templates and
|
|||
|
|
run: * Fedora: ``sudo dnf upgrade`` * Debian:
|
|||
|
|
``apt-get update && apt-get dist-upgrade``
