Good day, dear forum users! Several times this year the system refused to accept the correct user password. Healed by reboot. I used to encounter this when logging in (both through the console and through SDDM). But today for the first time the system refused to accept the password in the terminal (command sudo...). With what it can be connected? Please do not write answers indicating obvious reasons such as: Caps Loch, Num Lock, wrong keyboard layout, forgot how I changed it (and then returned it), etc.

Log-In works? Root Log-In? TTY terminal? Terminal Emulator inside DE?
Is your keyboard always perfectly functional?
Root Log-In works on every attempt?
Grab a journal from a non-working password attempt (you'll need to Root Log-In) and post here its output.
