I am newbie in working with KiCad So for first time i tried to generate footprint of one negetive voltage source from here and here: And the Sketch is like this :

button and i get this error in my linux LMDE like this:

i have also googled it and found some information like this (Error Encountered IO_ERROR: Footprint library path ) :

I have seen this error myself. So far on the Windows version at work. It is (nor can it be) connected to the Internet.

bobc Nov '16 The method kicad_plugin.cpp:FootprintEnumerate() is designed to load from a local folder, not a URL, so it will throw an error if it gets a URL.

I guess that could happen if you have a footprint table entry set to KiCad when it should be Github, or there is a bug in the cache handling in KiCad.

But i don't get any idea for solving it!!!

Also from installation KiCad for linux MINT in this site i get this suggestion:

If you prefer to use the shell, you can enter these commands into a terminal:

sudo add-apt-repository --yes ppa:js-reynaud/kicad-5.1 sudo apt update sudo apt install --install-suggests kicad This will perform a full installation of KiCad. If you don’t want to install all packages you can use:

sudo apt install kicad If you don’t do a "full installation" you should be interested to install also:

kicad-libraries: a virtual package that will recommend you to install footprints, symbols, templates and 3D

but i can not install this command:

i get this error:

so@notebook:~$sudo apt install --install-suggests kicad-libraries Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package kicad-libraries i also can not install new version byt this codes: sudo add-apt-repository --yes ppa:js-reynaud/kicad-5 i get this error: so@notebook:~$ sudo add-apt-repository --yes ppa:js-reynaud/kicad-5

So is there any what to install it by linux command code or i must reinstall it or add footprint libraries manually?

Well, the instructions are for Linux MINT. You are running LMDE. To quote from the LMDE announcement:

LMDE is less mainstream than Linux Mint, it has a much smaller user base, it is not compatible with PPAs, and it lacks a few features. That makes it a bit harder to use and harder to find help for, so it is not recommended for novice users.

The PPAs are derived from Ubuntu. Since LMDE is derived from Debian, you can't use them safely.

Neither Mint nor LMDE are officially supported distributions by the KiCad Project. If you plan on using KiCad for working with circuits, it may be advisable to use one of the supported distributions.

You may be able to use one of the Debian packages with LMDE but since there is no actual maintainer for the distribution, there may be many problems with this path.

If you just want the libraries, you should use:

\$ sudo apt-get install --install-suggests kicad
• Is it anyway to change the LMDE Linux to better distribution without losing my installed packages on it? – moha_alpha-web.net Oct 22 '19 at 22:08
• I can't say for certain. If I were doing that, I would run dpkg --get-selections and save the output to a file, then install those packages in the new distribution. – Seth Oct 22 '19 at 22:16

You did not include all the information you have here in the forum post (the screenshots are missing) which means i did miss that you run on v4.

If kicad itself runs and you only have trouble installing libs then you can always do this manually. However this is a bit harder with version 4 than with version 5.

To be honest at this point in time i would not install the normal v4 libs anyways but use the backported v5 libs. (https://github.com/KiCad/kicad-footprints/releases/tag/v4-backport-5.0.0, https://github.com/KiCad/kicad-symbols/releases/tag/v4-backport-5.0.0)
