You’re running HassOS with Home Assistant? (Old hass.io)? Or is it HA Supervised (HA on a generic linux host). If the latter, can you show the output of the df command. This error is normally lack of disk space.
HassOS with HA
ha > os info
board: rpi4
boot: B
version: "3.13"
version_latest: "3.13
ha > core info
arch: armv7
audio_input: null

version_latest: 0.109.4

watchdog: true
and while I was there, tried this command
and weird result was - its updated…
ha > core update
Processing... Done.
Command completed successfully.
Failed update was thru Web interface, and to 0.109.3 version
Login to the host (the host, not the HA container)
run
docker pull homeassistant/raspberrypi4-homeassistant:0.109.3
(or better run docker pull homeassistant/raspberrypi4-homeassistant:0.109.4)
and show the output of that command
Omg this worked. Thank you, did a fresh install and got the overlay2 error upon installing SAMBA.

Fixed it for me as well. Thanks a lot! 
Was updating supervisor and then when I tried to update HA from 0.112.0 to 0.114.0 I got the error.
Did the repair and was afterwards able to update HA.
Thanks again.
On supervised docker, you can run repair command:
docker exec -it hassio_cli /bin/bash
ha su repair
