Can't Install Kicad - Unmet Dependencies
|
Hi,
I'm trying to install Kicad on an Ubuntu 20.04 LTS machine. Following the (command line), instructions here: The installation fails with: Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies. kicad : Depends: libocct-data-exchange-7.3 but it is not going to be installed Depends: libocct-foundation-7.3 but it is not going to be installed Depends: libocct-modeling-algorithms-7.3 but it is not going to be installed Depends: libocct-modeling-data-7.3 but it is not going to be installed Depends: libocct-ocaf-7.3 but it is not going to be installed E: Unable to correct problems, you have held broken packages. I have run Kicad on this PC before. In fact I don't recall uninstalling it, but it's definitely no longer on the PC. Anyone know what is wrong? Regards, Robert. |

This is part of the 3D model system,, and it looks as if it's a problem
for other programs as well. See: What I suspect has happened is that the 20.04 release of Ubuntu may not have these installed as standard. If you get really syuck with this there ius a flatpak version of kicad on flathub It will mean a thumping big download, but it will have all the dependencies sorted out. (You should be Ok by just installing the libccct stuff) Andy On Wed, 22 Sep 2021 17:46:36 +0100 "Robert" <birmingham_spider@...> wrote: Hi, |

FollowingI just checked on my own installation of KiCAD on Ubuntu Focal: this library is in focal/universe. The relevant line in /etc/apt/sources.list would be: deb focal main universe (replace "de" with whatever mirror you use; optionally followed by: restricted multiverse) If you already have universe in your config - try a different mirror, maybe yours has synchronization issues. Worst case: download those packages manually from the archive and install them with dpkg. You can also use "apt-cache depends" to find out what the dependencies of those libs are and whether those might have a problem (apt-cache policy). ??? hope that helps, ??? Konrad |

Thank you for your replies. Manually installing the libraries got me
no further. Turns out there is an incompatibility between Freecad 0.19 and Kicad, which is clearly a significant issue. Removing Freecad allowed the Kicad installation to start. Unfortunately, just to compound my misery, I was well into Kicad re-installation when my disk drive died; it's completely inaccessible. What a splendid way to start the day. Had that not been the case, my next step was going to be installing Freecad 0.18, which apparently is compatible with Kicad. I would give the URL for where I got this information, but I can't because that information disappeared with my disk drive. Just as well my biological disk drive continues to func -- This email has been checked for viruses by Avast antivirus software. |

That is odd. I have Freecad 0.19 with KicadStepUp and Kicad 5.1.10 running side by side on top of Ubuntu 20.04 LTS, upgraded from 18.04 LTS. I never add any compatibility problem. In a recent project I spend a couple of weeks working with both programs at the same time, going forth and back between designing components and exporting models. No problems at all.

My experience and a lot of chatter in the forum about this. It appears KiCAD and FreeCAD can get into a situation where one has installed a different version of the OpenCascade kernel they both depend on for 3D modelling. If, for whatever reason, the OCC version is higher than that expected by KiCAD, the install won't proceed. On Thu, Sep 23, 2021 at 6:58 AM Jorge Ferreira <jorgef.tech@...> wrote: Hi |
