It’s no secret that the officially maintained repository for Ubuntu can get out of date quickly. A lot of software developers/houses are now letting you install applications straight from their repositories.
Ubuntu makes this possible with PPAs or “Personal Package Archives” (https://launchpad.net/ubuntu/+ppas).
So – how do you add a PPA to your system and then hence then add the application. Well, you can use the GUI method (https://askubuntu.com/questions/4983/what-are-ppas-and-how-do-i-use-them), or if you’re more like me – the command line version:
me@machine:~$ sudo add-apt-repository --yes ppa:js-reynaud/kicad-4 me@machine:~$ sudo apt update me@machine:~$ sudo apt install kicad
Where “ppa:js-reynaud/kicad-4” is the name of the PPA, and “kicad” is the name of the package/application you wish to install. Hey presto – press”Y” where appropriate and it’s done!
Yes, if you’ve not already guessed, I’m installing KiCAD (http://kicad-pcb.org/) to try as an alternate to Eagle.
