I’m using Kubuntu 21.10 (kernel 5.13.0-40-generic) with LUKS encrypted partitions that are unlocked by password + Yubikey4 ver 4.3.7.
Every so often I get
yubikey core error: no yubikey present when trying to unlock the system.
When this happens it’s usually enough to just retype the password and then it proceeds normally.
Anyone have similar issues? Also I’ve noticed that sometimes Yubikey does not blink its LED when connected, which makes me think that this can have something to do with USB.
I’ve seen similar messages on the net, but they’re mostly about Yubikey not working at all because of wrong libraries and/or misconfiguration.
