Sam - slightly different topic. My other sd card installed in a rasp p2 did it’s update correctly and then I was asked to close kodi to allow update to complete. Got an error message as follows
Error installing rbp2.mediacenter.osmc (184.108.40.206). Please report on OSMC forum.
I noted that my wireless connect had been lost and would not allow me to manually reinstall. I shut down osmc and opened it again and got black and white text all over main screen until I got an unhappy face.
Was able to ssh into osmc and did a fsck and it went through a mammoth fix including multiply claimed blocks shared with one file /usr/share/kodi/addons/skin/.confluence.
End result was that everything seems to be properly updated and working fine but thought you should know.
