Hi friends! Has anyone here had success using Yubikeys on Linux? I’ve been going back and forth with support to no avail, trying to get my Yubikey 5C NFC to play nicely on Ubuntu 22.04 LTS. Any suggestions are appreciated.
I have the following Yubikey-related packages on my system:
libyubikey-udev 1.20.0-3 [Ubuntu/jammy universe]
├── is installed
└── udev rules for unprivileged access to YubiKeys
libyubikey0 1.13-6 [Ubuntu/jammy universe]
├── is installed
└── Yubikey OTP handling library runtime
python3-yubikey-manager 4.0.7-1 [Ubuntu/jammy universe]
├── is installed
└── Python 3 library for configuring a YubiKey — transitional package
yubikey-manager 4.0.7-1 [Ubuntu/jammy universe]

└── Python library and command line tool for configuring a YubiKey

├── is installed
└── Graphical application for configuring a YubiKey
yubikey-personalization-gui 3.1.24-1build1 [Ubuntu/jammy universe]
├── is installed
└── Graphical personalization tool for YubiKey tokens
libfido2-1 1.10.0-1 [Ubuntu/jammy main]
├── is installed
└── library for generating and verifying FIDO 2.0 objects

└── Python library for implementing FIDO 2.0
pcscd 1.9.5-3ubuntu1 [Ubuntu/jammy universe]
├── is installed
└── Middleware to access a smart card using PC/SC (daemon side)
UPDATE: After working my way down the entire software stack, I contacted the vendor of my USB-C port and requested a replacement. It did the trick…
Did you check their support guides https://support.yubico.com/hc/en-us/articles/360016649099-Ubuntu-Linux-Login-Guide-U! ?
I’m on Debian, but I think I’ve only ever used mine in Librewolf. But I can verify it works fine for me in the browser.
I use my Yubikeys all the time in OpenSUSE Tumbleweed and Linux Mint - a Yubikey 5 NFC and a Yubikey 5C NFC (mostly with Firefox). I have never had any problems with them. Mint is Ubuntu-based so they ought to work in Ubuntu. Sorry I can’t advise you on why yours isn’t working, but it should definitely be possible to get it working.
Tumbleweed user here. Thinking of buying a yubikey; is it easy to setup for logins etc or does it involve terminal commands etc. I mean is there a repository app?
I’m afraid I can’t remember how I did it, it was some time ago on a machine I no longer have. There is some advice here:

There’s an appimage for their manager app there. You might also try using Distrobox to give yourself access to a distro that uses apt, and then add Yubico’s PPA and install the software from there. I don’t know whether it would work but in principle it should.
I used to use one without any issues, it wasn’t the 5 series but it had NFC. The worst part was setting up to use it as an ssh key. Just normal 2FA with it worked straight out of the box (firefox/arch). Is that what you’re trying to do?
Are you talking about 2FA login for your own user account or U2F/PIV/WebAuthn in your browser? The latter seems to work out of the box on any non-snap or flatpak browser, but the former needs a bit more setup as that is not a standard feature in Ubuntu yet. I recommend using ykman and yubico-piv-tool for configuring yubikeys in linux, but Yubico also provides a GUI application on their website
