Installing GNS3 on Ubuntu 10.04 Lucid Lynx
First.. a general disclaimer.
If this does not work for you, please dont ask me for tips/help/support. This is provided for information only. If this does not work for you then Im sorry. Furthermore, some of these steps may be superfluous or unnecessary but all I know is they worked. Someone else (the same guy you ask to fix (who is not me) if your install does not work) may be able to streamline this process or explain better.
OK… this is what I did:
sudo apt-get install dpkg-dev # this downloads some kind of unpacking tool
sudo apt-get source gns3 # downloads source files, probably unnecessary as I think the next step does that too, but by that stage it was too late
sudo apt-get install gns3 # does all the work
profit # dont type this in
