Hi, I've used linux for several years but still feel a newbie in many areas, so I hope this post is suitable for this forum. I recently installed linux Mint14 (+Mate) on my laptop. All seemed well until I needed to install the gmt (general mapping tools) package. I tried this with sudo apt-get install and subsequently with the package manager GUI. In both cases I was told that the installation had failed because of dependency issues involving qmail. (Incidentally I had the same problem when trying to install the mahjong game, but I can live without that.) Now I do not really know what qmail is, nor why it is involved in this process or the package, but looking into the detailed error report, it said that I needed a fqdn. I do not really know what this is either, nor how it is set, nor why I have not hit this problem before (in Ubuntu 10.04 and earlier distributions), but a websearch suggested to me that maybe there was something missing from my /etc/hosts file. In case that is relevant, the content of /etc/hosts is QUOTE 127.0.0.1 localhost 127.0.1.1 Dell-Lap2011 # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ENDQUOTE I would be grateful if anyone could tell me what all this is about and how I solve the problem. Thanks
