Comment 8 for bug 1660633

Meanwhile in https://answers.launchpad.net/ubuntu/+source/ucf/+question/448737 we identified two areas where the ucfr script misbehaved in the environment of the original poster.

The following workarounds helped:

Change all occurrences of $" into "'$'
Change all occurrences of egrep into grep -E

Even if we do not know why the ucfr script failed in the original poster's environment, these modifications might be worth being considered for future versions of the ucfr script.
