I am working on Devuan Chimaera and I have installed it by (https://github.com/casualsnek/cassowary … install.md):

pip install cassowary

    Install python3, python3-pip, freerdp2, libvirt-python3 packages and dependencies by running following commands on terminal:

$ sudo pacman -S python3 python3-pip freerdp libvirt-python
$ pip3 install PyQt5

But after that I received:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package freerdp is a virtual package provided by:
  freerdp2-x11 2.3.0+dfsg1-2+deb11u1
  freerdp2-shadow-x11 2.3.0+dfsg1-2+deb11u1
You should explicitly select one to install.

E: Package 'freerdp' has no installation candidate
E: Unable to locate package libvirt-python
root@Think-Desktop:~# pip3 install PyQt5
Requirement already satisfied: PyQt5 in /usr/lib/python3/dist-packages (5.15.2)
Requirement already satisfied: PyQt5-sip<13,>=12.8 in /usr/lib/python3/dist-packages (from PyQt5) (12.8.1)

What to do? and what to print in terminal?
