recurring ttf-mscorefonts-installer popup - andale32.exe not found

[Sebastian Wiesendahl]

since a week or so the update-notfier is complaining that the download of additional files has failed:

```lang=en
# Update information

Failure to download extra data files

The following packages requested additional data downloads after package installation, but the data could not be downloaded or could not be processed.

ttf-mscorefonts-installer

The download will be attempted again later, or you can try the download again now. Running this command requires an active Internet connection.

```

```lang=de
# Hinweise zur Aktualisierung

Herunterladen von zusätzlichen Datendateien schlug fehl

Die folgenden Pakete benötigen nach der Installation das Herunterladen zusätzlicher Daten, welche aber nicht heruntergeladen oder bearbeitet werden konnten.

ttf-mscorefonts-installer

Das Herunterladen wird später erneut versucht, oder Sie versuchen es jetzt gleich nochmal. Das Ausführen dieses Befehls benötigt eine aktive Internetverbindung.
```

This bug seems similar to https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/979477

where it was considered to look up the following:

```sh
$ sudo /usr/lib/update-notifier/package-data-downloader
ttf-mscorefonts-installer: processing...
ttf-mscorefonts-installer: downloading http://downloads.sourceforge.net/corefonts/andale32.exe

E: Failed to fetch https://vorboss.dl.sourceforge.net/project/corefonts/the fonts/final/andale32.exe 404 Not Found

```

And here is a workaround proposed by "Kätzchen", but seems to be of static nature and may break things:

https://forum.ubuntuusers.de/topic/update-probleme-mit-ttf-mscorefonts-installer/

```sh
wget http://ftp.de.debian.org/debian/pool/contrib/m/msttcorefonts/ttf-mscorefonts-installer_3.6_all.deb
sudo dpkg -i ttf-mscorefonts-installer_3.6_all.deb
```
