OS update problems: "Can't open file" and widgets gone

I open this new topic because I think it would be difficult to continue the discussion in a thread with > 200 contributions, and growing.

Continuing the discussion from Software update Kola Nut 1.8:

Disclaimer: I can’t properly respond in Dutch, and I have not yet updated the FP OS to 1.8 “Kola Nut”. (But I’ll try to help, anyway.)

  • First, could you check in the Fairphone Updater app which version you are currently running?
  • Then, could you, while being connected to WiFi, tell us what the Fairphone Updater app shows you (or maybe post a screenshot)?
  • Furthermore, did you run a backup? If so, which backup app did you use?
