You did an 'apt-get update' before trying to install, right?
Oops. Nope.
Assuming you did, your repositories might still be misconfigured or missing. Try the'apt-cache policy' command to see if synaptic is found.
[root@dhcppc5 root]# apt-get upgrade Reading Package Lists... Done Building Dependency Tree... Done 0 upgraded, 0 newly installed, 0 removed and 0 not upgraded. [root@dhcppc5 root]# apt-get install synaptic Reading Package Lists... Done Building Dependency Tree... Done E: Couldn't find package synaptic [root@dhcppc5 root]# apt-cache policy synaptic W: Unable to locate package synaptic [root@dhcppc5 root]#
Suggestion: if you install apt-get from Dag Wieers' repo, it comes with many useful repos pre-configured, each on its own .list config file on /etc/apt/sources.list.d dir.
I downloaded it from the link in the wiki, whereever that was. I'll see if I can find the one you mention.
