While trying to update my GitHub site, I got an error about a symbolic link being missing in my default.html. This was strange since I didn’t have a default.html file. The problem was a recent update to the Minima theme which the site uses.

The Minima update made incompatible changes relative to my custom footer.html. The GitHub error message was misleading. I solved this by finding icon-github.html and icon-github.svg on the web. But this didn’t look very nice. Instead I updated my custom footer.html to the revised Minima version. But the new version includes other files as well. To prevent this problem from occuring again, I removed the included file, as well as customizing the appearance of the footer.
