Comment 7 for bug 1655565

Sigh. Your first two downloads worked though, the third one failed. You should report this on bug 1651923, Julian Klode might be able to help. The error message you get now, "Protocol http not supported or disabled in libcurl", is symptomatic of the same bug 1607535/1651923 I suggested as a duplicate, just like the error "404 Not Found". The error message depends on the contacted mirror.

In particular, see Elvis Stansvik's comment 25 in bug 1651923: he got the same error message as you from the vorboss.dl.sourceforge.net mirror even after he upgraded apt-transport-https to 1.2.19.

You can use apt-helper for tests instead of reinstalling ttf-mscorefonts-installer over and over again (line breaks for readability only):

$ /usr/lib/apt/apt-helper
    [-o debug::acquire::https=1 -o debug::acquire::http=1]
    download-file
    http://downloads.sourceforge.net/corefonts/andale32.exe test.exe
    OR
    "https://people.debian.org/~jak/a b/c" test.exe

The optional part is for debug output.
