I have this problem still. What I found to work was to remove the failed install and install it using the deb. I wrote an article about it on my blog for future reference... https://computerobz.wordpress.com/2016/12/15/ttf-mscorefonts-installer-fails-to-installupgrade/
Basically: 1.) Launch a terminal and remove the failed install: sudo apt-get remove --purge ttf-mscorefonts-installer 2.) Get the package and install it using the following three commands: cd ~/Downloads/ sudo wget http://mirrors.linux.iu.edu/linux/debian/pool/contrib/m/msttcorefonts /ttf-mscorefonts-installer_3.6_all.deb sudo dpkg -i ttf-mscorefonts-installer_3.6_all.deb Problem solved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1651923 Title: apt https method decodes redirect locations and sends them to the destination undecoded.
