[SOLVED] [kicad] Fails to open pcbnew with Python 3.9.1

I am having the same problem as outlined in this bug report which was closed.

https://bugs.archlinux.org/task/68904

When starting pcbnew, I'm getting the following messages:

libpython3.8.so.1.0: cannot open shared object file: No such file or directory
Failed to load kiface library "/usr/bin/_pcbnew.kiface"

It looks like Python 3.8 got replaced by 3.9 recently.

Additional info:
* Kicad 5.1.8-3
* Python 3.9.0-1

Steps to reproduce:
* Run `pcbnew`

I also get it when picking schematic symbols in the schematic editor but the program does not crash completely.
Any help would be greatly appreciated!

Edit: My kicad-git version is: 5.99.0-7115-gd59053b775 and python 3.9.1

Any reason why your kicad is not up to date? Version 5.1.9 was published on 23 December.

Re: [SOLVED] [kicad] Fails to open pcbnew with Python 3.9.1

Reinstalling kicad git using

yay -S kicad-git

and doing a clean build worked for me. I guess the dependency reference needed to be compiled into KiCAD?

New version for me: 5.99.0-8413-g54cf67dad2
