Runtipi update from 4.8.2 to 4.9.1 did not work as expected

“failed to get docker version: exit status 1”. The system seems to be working, but does not show as being updated and still shows the update available on the runtipi home screen.

Following is the output from the update. Unable to post output from debug command due to new user status in the forum.

ned@tipi:~$ cd runtipi
ned@tipi:~/runtipi$ ./runtipi-cli update v4.9.1
✓ Runtipi updated successfully. Starting new CLI
✗ failed to get docker version: exit status 1

Error: failed to get docker version: exit status 1
ned@tipi:~/runtipi$

Thanks in advance for any help or tips you can provide.
