Updates REMOVED all apps and can't restore

Hi Aleks, thanks for your quick reply!
Let’s see, so the command you suggest gives:

root@ihost:~# dpkg --configure -a
Setting up docker-ce (5:19.03.1~3-0~raspbian-stretch) ...
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.

This message makes me think of the time when I tried installing Collabora and Docker didn’t work out. (Problèmes éditeurs de texte collaboratif)

Are you able to understand the message? Thanks again!
