Default fonts are missing in chromium after a snapd update
Nothing happens if I quit and reopen chromium the usual way, the fonts are still missing
But if I run a ‘sudo killall chrome’ command instead of simply quitting chromium then the fonts are no longer missing.
(same approach here: How to run chromium in another language?)
I don’t know if this is the logical approach but in any case it saves me tedious manipulations.
