loading freecad addon "fasteners" will fail

[Ventusfahrer]

Hi there!

I was installing the Freecad AddOn Fasteners from the AddOn store.

When trying to load the Addon via Edit -> Preferences -> Workbenches -> Press Load Button behind Fasteners, the UI fires a popup

The terminal output contains a little more information:

freecad

    matchOuterButton.setCheckable(True)

freecad version is:

$ snap list freecad
Name     Version        Revision  Tracking     Herausgeber  Hinweise
freecad  1.1-g8865450a  1180      latest/edge  freecad-org  -

The corresponding weekly appimage from the download aerea is working fine.

kind regards

@furgo16 can you reproduce? (I'm having issues with Snap ATM and can't test)

[Ventusfahrer]

my current OS is:
Ubuntu 24.10 with all current updates installed.
I can reproduce the problem on two computers (desktop and noteboot) both running with the same OS-Version

@luzpaz thanks for the heads up. I can reproduce:

This is not specific to the snap package. I get the same behavior from the daily PPA (.deb package):

'NoneType' object has no attribute 'setCheckable'

@luzpaz is it worth moving this issue to the main FreeCAD repository, or to the Fasteners workbench one?
