我在新安装的 12.04 LTS 上使用以下命令集。
sudo apt-get install -qq python-software-properties
sudo add-apt-repository -y ppa:v-kukol/mono-testing
sudo apt-get update -qq > /dev/null
sudo apt-get install -qq mono-complete mono-gmcs > /dev/null
mozroots --import --sync
但是，该mozroots命令失败，并显示以下错误消息。

当我使用 Mono 2.10.8.1（12.04 的默认版本）时，我没有遇到这个问题。但是，我现在需要为我的应用程序添加一些 Mono 的新功能。
我该如何解决这个错误？
