Hi, After I sucessfully installed parental control software it keep saying my clamav is outdated.when I am trying to upgrade it, I am getting this error.need your help. shankar@firewall:~$ sudo apt-get install clamav Reading package lists... Done Building dependency tree... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation: The following packages have unmet dependencies:   clamav: Depends: libclamav1 (>= 0.88.7) but 0.88.4-1ubuntu1~dapper1 is to be installed E: Broken packages shankar@firewall:~$ sudo apt-get dist-upgrade Reading package lists... Done Building dependency tree... Done Calculating upgrade... Done The following packages have been kept back:   clamav libclamav1 0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded. shankar@firewall:~$ thanks -- Shankar
