[qubes-users] Q: Problem updating whonix-gw (sdwdate)

Hi!

Upgrading the whonix-gw template resulted in an unexpected error:

Updating Qubes App Menus and advertising features...
Processing triggers for desktop-file-utils (0.23-4) ...
Processing triggers for tex-common (6.16) ...
Running updmap-sys. This may take some time... done.
Running mktexlsr /var/lib/texmf ... done.
Building format(s) --all.
  This may take some time... done.
W: APT had planned for dpkg to do more than it reported back (570 vs 575).
    Affected packages: texlive-latex-base:amd64
+ true 'INFO: Install pre release upgrade of dependency packages (2/2)...'
+ apt-get-noninteractive --yes --no-install-recommends install sdwdate

The following information may help to resolve the situation:

The following packages have unmet dependencies:

E: Unable to correct problems, you have held broken packages.
+ true 'ERROR: An error was encountered during download of dependency packages. Recommendation:
Fix network connection and retry.'
+ exit 1

I'm kind of clueless what to do. The recommended fix did not work:
ser@host:~$ sudo apt-get-noninteractive --yes --no-install-recommends install sdwdate
Reading package lists... Done
Building dependency tree
Reading state information... Done

Ideas?

Unfortunately, as it turned out later, whonix-gw has not network for updates any more (while tor seems operational), and whonix-ws also has no network any more.
It seems something went very wrong while updating.
Unfortunately I have very little experience how to fix Qubes networking.
