Ubuntu: All of KiCad deleted?

Software
1

I’m sure this must be user error, but for the life of me, I can’t figure it out. Today, when I went to use KiCAD, it couldn’t be found. There was no trace of the kicad software on my system. I had used it less than a month earlier, so I was really puzzled.

I found this evidence in /var/log/apt/history.log.1:

Start-Date: 2024-01-29  14:47:47
Commandline: apt-get autoremove

End-Date: 2024-01-29  14:47:50

Earlier, in that same history file, I found:

Start-Date: 2024-01-04  10:43:34
Commandline: apt-get upgrade
Requested-By: kevin (1000)
Upgrade: kicad-demos:amd64 (7.0.9~ubuntu22.04.1, 7.0.10~ubuntu22.04.1), kicad:amd64 (7.0.9~ubuntu22.04.1, 7.0.10~ubuntu22.04.1), r-cran-cluster:amd64 (2.1.5-1.2204.0, 2.1.6-1.2204.0), r-cran-mgcv:amd64 (1.9-0-1.2204.0, 1.9-1-1.2204.0), r-cran-rpart:amd64 (4.1.21-1.2204.0, 4.1.23-1.2204.0)
End-Date: 2024-01-04  10:43:40

This seems normal at this point, and shows that kicad was there.

However, this immediately proceeded the delete by one day (look for ‘kicad’ in the remove line):

Why would installing libocct*-dev cause kicad to be marked and removed? libocct is the Open Cascade Technology library, which I think I installed to work with either FreeCAD or Inkscape-Ink/Stitch. Is this a problem to take up with the libocct developers?

Thanks for any thoughts on this puzzling occurrence.

I’m guessing that I have to uninstall libocct* before I can proceed with the kicad reinstall. Any thoughts?

Will be fixed once 7.0.11 is released; for now install the 7.0 testing PPA.

FreeCAD updated their OCCT dependency and now it’s incompatible with the one KiCad 7.0.10 and below use.

There is an easy workaround. I don’t know if it will screw up freecad but I have freecad installed as well and it seems to work fine. Theshould install the correct version of occt-misc:

sudo apt-get install occt-misc=7.6.3+dfsg1-7

@craftyjon, thank you so much. That worked like a champ.
