Yubikey Manager stuck at "Insert your Yubikey" reporting "NameError: name 'yubikey' is not defined" → "Function not found: 'yubikey.controller.count_devices'"

I'm on Ubuntu 20.04 with deb http://ppa.launchpad.net/yubico/stable/ubuntu focal main enabled.

$ apt show yubikey-manager-qt
Package: yubikey-manager-qt
Version: 1.1.3~ppa1~eoan1
Status: install ok installed

The Yubikey Manager stopped working at some time. Possibly due to some ykman update? ykman itself is working without issues.

It is stuck at the "Insert you yubikey" screen. Starting it from CLI keep repeating the following output into the console:

 $ ykman-gui

Uhhh… just realized that it's no longer up-to-date and using the AppImage works. Related to #238. My bad.

As I already mentioned in I find the lack of system integration with AppImage frustrating. Next time the App stops working I'll probably find myself opening another issue here until I realized how & when & why I need some specific Voodoo only for this app to keep it running.

I understand the packaging pain, but Snap and Flatpak distributions at least offer System Integration (i..e launch menu) and an (automated) update-facility.

@bentolor As you have pointed out, the AppImage is the supported distribution format for Linux. I understand that this might not be ideal. If there is a community effort to package for something else we will try to help out as much as we can. I also want to point out that if you are comfortable using the terminal, we have a CLI .
