Cannot unlock screen after manual lock in Ubuntu 17.04 with Unity
I have recently reinstalled Ubuntu 17.04 on a new laptop using full disk encryption, having forgotten to enable it the first time.
To save some time on configuration, I created a backup of my home complete directory and restored it in the new installation.
When I start the laptop I can login without any problem, but if the session get's locked I can't log back in again as usual and I get a "wrong password" message.
Using the terminal via CTRL+ALT+F1 accepts the password every time. It also works as a workaround to click "Change User" in the graphical session and then log back in.
I haven't yet found any useful information in any log files.

It seems that a misguided try to restore the backupped /etc direcory caused the error. as Lock screen - password incorrect suggests, the /etc/gshadow and /etc/shadow were owned by root:root instead of root:shadow.

I had the same issue on Ubuntu 18.04 + Gnome desktop + lightdm.
But initially, I switched back to gnome from unity and left lightdm as is, so when I had second language enabled and lock the screen it seems that Ubuntu didn't switch language to English properly. So I managed to create additional user with digits-only password to reset my main account password when it happens.
Then I though that display manager may be the issue, so I've switched back to gdm3 and all worked normally.
(trying to be more clear, probably I'll try to reproduce that)
- Install Ubuntu 18.04
- sudo apt install ubuntu-unity-desktop
- select lightdm as a default window manager
- return back to gnome
- switch keyboard to the second language
- lock the screen by Win+L
- Password is incorrect
sudo dpkg-reconfigure gdm3, choose gdm3, reboot or re-login- lock screen in any active keyboard language
- Password working as a charm
If I'm not the only one, that should be reported to Ubuntu bugs, surely
