LibraZiK-4 Manual - Installing a software


We have seen that Synaptic is the package manager of choice for your LibraZiK-4 environment. It goes even further than that, it is very strongly discouraged to install a software other than through Synaptic because, in the best case, it may work, and then that's great, but in other cases, it may mess up and even rot your system to the point where a complete reinstallation will be necessary. You'll find plenty of reading material on the web that will give you instructions on how to install software X or Y. Don't follow them if they don't start with “open your Synaptic package manager”. When in doubt, contact us to ask us what we think of this or that installation procedure that you will have gleaned from the Internet.

You will have been warned! 8-)
