# Description: Script to install Microsoft Vista TrueType Fonts (TTF) aka Microsoft’s ClearType fonts on Ubuntu distros | |
# Microsoft added a group of new "ClearType Fonts" to Windows with Windows Vista and Office 2007. | |
# These fonts are named Constantia, Corbel, Calibri, Cambria (and Cambria Math), Candara, and Consolas. | |
# Calibri became the default font on Microsoft Word 2007, and it’s still the default font on Word 2016 today. | |
# Dependencies: wget, fontforge and cabextract | |
# Note: Microsoft no longer provides the PowerPoint Viewer 2007 (v12.0.4518.1014) or any version anymore for download | |
# Tested: Ubuntu Saucy/Trusty/Xenial/Bionic |

For troubleshooting, two things to first try: | |
run `git config --global gpg.program gpg2`, to make sure git uses gpg2 and not gpg | |
run `echo "test" | gpg2 --clearsign`, to make sure gpg2 itself is working | |
If that all looks all right, one next thing to try: | |
run `brew install pinentry` to ensure you have a good tool installed for passphrase entry | |
If after that install and you re-try git commit and still get the "failed to sign the data" error: | |
run `gpgconf --kill gpg-agent` to kill any running agent that might be hung |
