As stated in comments on the other answer here, you have in fact no Arial font installed other wise fc-match Arial
would state the following:
$ fc-match Arial
Arial.ttf: "Arial" "Regular"
Edit: as @Anwar stated in comment fc-match
can yield a false result,
so to be sure do as well an fc-list Arial
which should yield an output
like the following:
$ fc-list Arial
/usr/share/fonts/truetype/msttcorefonts/Arial_Italic.ttf: Arial:style=Italic,Cursiva,kurzíva,kursiv,Πλάγια,Kursivoitu,Italique,Dőlt,Corsivo,Cursief,Kursywa,Itálico,Курсив,İtalik,Poševno,nghiêng,Etzana

So to make sure it is really properly installed (the usual command runs sadly in 404 errors during installation) do the following:
apt remove --purge ttf-mscorefonts-installer
This removes the current installation. Just doing this to make sure we accept the EULA in the next following installation dialog.
sudo apt install ttf-mscorefonts-installer
It most likely gives you while installing a few error messages while installation, stating that it can't fetch the font from sourceforge.net.
To work around this simply do the following:
TMP=$(mktemp -d)
cd "$TMP"
awk '/Url/ {system("wget "$2)}' /usr/share/package-data-downloads/ttf-mscorefonts-installer
sudo /usr/lib/msttcorefonts/update-ms-fonts "$TMP"/*
sudo touch /var/lib/update-notifier/package-data-downloads/ttf-mscorefonts-installer
This is should result in a fairly long output processing all the Microsoft fonts and updating them. All now needed to do is cleaning up.
cd ..
rm -r "$TMP"
To test now do an fc-match Arial
again which should now yield the above stated result.
tts-mscorefonts-installer
. I clicked on install. It did flash me that some EULA wasn't signed or something. But the installations completed.fc-list 'Arial'
?
