Hi all, I have an LTSP server running Jaunty. I want to install apticron on the server. Apt wants to install an MTA along with apticron which is fine with me, however it wants to install postfix AND exim4 and it also warns that the packages cannot be authenticated. Can someone help me understand why this might be happening.
Here's the message from APT and below that I've pasted the contents of /etc/apt/sources.list Thanks! John cbuntu:~$ sudo apt-get install apticron Reading package lists...
