Description

I use "cura" for 3D printing. It worked yesterday before the last Solus updates. Now I get the following error:

$ cura
Error in sys.excepthook:

Just passing along some information. A friend of mine also encountered this, he resolved it by running
sudo pip3 install sip

Even tho the python-sip and python3-sip are installed from the repository.

sudo pip3 install sip fixes the issue.

Thank you!
