Steps to reproduce

Scratch install of linux mint

sudo apt-add-repository ppa:yubico/stable
sudo apt update
sudo apt install yubikey-manager

Expected result

Ykman to display

Please note this also happens on similarly version ubuntu machines. I use a test linux mint image to confirm all authentication for yubikeys before we upgrade our machines.

I'm unable to reproduce this using a stock Ubuntu 22.04 image. I see that Python 3.12 is part of the path in your stacktrace, which isn't normally available in Ubuntu 22.04. Are you manually installing a newer Python version, and if so, through which method?

[dainnilsson]

I did a little digging and I am able to reproduce the issue by forcing ykman to use Python 3.12, which can happen if you for example change the /usr/bin/python3 binary on your system:

The PPA installation is tied to Python 3.10, so you will either have to manually adjust the symlink in /opt/venvs/yubikey-manager/bin/ to point to python3.10, or install yubikey-manager using a different method, such as pip.

Linut Mint 22 is based on Ubuntu 24.04. My installs with 22.04 everything does work correctly. The default python on the newer versions is 3.11<

Pip install is also broken (this is merely opinion and not fact). I understand this piece is nitpicking and it's stated in instructions pcslite is needed but for your average user I would explicitly put the commands/instructions on help pages or directly in the python package as a requires.

Installling libpcsclite manually will fix this.

apt install libpcsclite-dev

Some of the above comments are for other users searching for the bug. I have a path forward for our upgrade process nonetheless.

[dainnilsson]

Ubuntu 24.04 (or derivatives) should use the correct PPA package, but your first post shows the package for jammy being installed rather than for noble. With a fresh Ubuntu 24.04 and the correct package installed the proper Python version will be used:

@dainnilsson Great catch! I've been staring at packages for the last 3 days and missed this. Ignore my earlier comments, this wasn't even coming up in package options.

Probably a bork during mint 21 -> 22 upgrade.
