Public bug reported:
If ttf-mscorefonts-installer is installed non-interactively, then the
EULA isn't accepted. After that, cron.daily sends this email every
single day:
>/etc/cron.daily/update-notifier-common:
>ttf-mscorefonts-installer: processing...
Note how there's no indication here of any error or any other
explanation for why this is running (and apparently not succeeding)
every day. It's because the downloader for the package silently fails to
download any fonts if the license hasn't been accepted.
Note this stanza at the end of /usr/share/package-data-downloads/ttf-
mscorefonts-installer:
>Script: /usr/lib/msttcorefonts/update-ms-fonts
>Should-Download: msttcorefonts/accepted-mscorefonts-eula
On a system where the package was installed non-interactively,
msttcorefonts/accepted-mscorefonts-eula is false.
The code which silently refuses to download fonts if that setting is
false is in /usr/lib/update-notifier/package-data-downloader:
> if 'Should-Download' in para:
> db = debconf.DebconfCommunicator('update-notifier')
> try:
> should = db.get(para['Should-Download'])
> if should == "false":
> # Do nothing with this file.
> break
> except:
> pass
> finally:
> db.shutdown()
Something at some level in this stack needs to produce some sort of
visible error message so that the user knows what the hell is going on
and can fix it.
However, on the subject of fixing it, there's another problem... maybe
I'm missing something, but I can't find any supported way of accepting
this license once the package has been installed, because the code that
prompts the user to accept the license is in /var/lib/dpkg/info/ttf-
mscorefonts-installer.preinst, and as far as I can tell, dpkg-
reconfigure doesn't rerun preinst files.
I'm not sure there is a simple fix here; I think perhaps some thought
needs to be put into significantly reworking how all this hangs together
in the case where the package is installed non-interactively.
In case you're curious, the reason why it's installed interactively in
my case is because I used ansible to install it. My workaround for this
issue was to add code to my ansible playbook to set the dpkg variable to
accept the EULA before doing the package install. But it took me hours
of digging through source code, scripts, etc., to get to the point where
I was able to figure out what was going on and what the workaround
should be. This is why I said above that at the very least there should
be a visible, useful error message in the cron.daily output.
