I was attempting to install Eagle 5.7.0 on the TinyOS computer through http://packages.ubuntu.com/. This website downloads self-installing packages to the computer. The installer for eagle complained about the version of libfontconfig1 being out of date, so I downloaded a later version of that, and attempted to install it. This complained about libfontconfig1-dev being out of date. I downloaded this package, and attempted to install it. This complained about libfontconfig1 being out of date again. I used Sympatic package manager to uninstall the current version of libfontconfig1, and intended to reinstall them from the downloaded packages.
The uninstalled packages were:
libfontconfig1, libfontconfig1-dbg,libfontconfig1-dev.
In the last parts of the uninstall, the computer froze, and I had to reboot. Upon rebooting, it said there was a file system mount error, and a maintenance terminal was started. Everything that was there previously seemed to be in place, so I did not want to reinstall the operating system, which would probably result in all of that being deleted. If there is a way to reinstall these packages via a utility shell, please let me know.
