How do I get past this error message, so I don't keep seeing the ttf-mscorefonts-installer error popup?
It's NOT the licence acceptance issue, apparently. It seems to be that the http protocol has been deprecated in libcurl, and the installer is trying to access an exe file from a http website.
sudo apt-get install --reinstall ttf-mscorefonts-installer
