I have the same issue, my Yubikey is the yibikey neo 4 model, it does support U2F. after installing Ubuntu 18.04.01 I followed yubico's instructions: https://support.yubico.com/support/solutions/articles/15000006449-using-your-u2f-yubikey-with-linux

which means I have a udev rule for the device, but dmesg was still mapping to snap.chromium. At this point the U2F seemed to wait for input until timeout, whereas the key's LED would flash like if it were in process of system recognition indefinitelly (as seen from dmesg, it seems chromium it continously attempting to read the device, but there are permission restrictions).

dmesg:

I have attempted as instructed in #9, the results are as described in #4: the U2F solicitors (github, gmail) will report "somethig whent wrong" as soon as the key is inserted. Thus it seems the issue got worse. BTW how do I get back to the default channel?
