DSA key errors with yum install in coLinux

  • Champs,
    I am facing issues the following issue with installing all apps in coLinux:
    -- When using yum install the installation fails at last step with  DSA key errors.

    Additional observations
    -- Error is seen when yum install is done from konsole terminal but works fine when yum install is done from a putty terminal (using ssh)

    Version Info:
    Cooperative Linux version: 0.7.4
    Linux version:
    Distribution: Fedora Core 10.

    Your insight would be greatly appreciated.
